We need a backtrace to hack code.

Hi Deep-Sea,

To do a backtrace on Windows, open a command prompt and change directory (cd)
to where you installed digikam (probably c:\Program Files\digikam or c:\Program
Files (x86)\digikam) then cd into 'bin'. Then do the following:

Type

   gdb digikam

and press 'Enter'

Once gdb launches type the following, changing the path to the log file as
desired:

   gdb digikam
   set logging file c:\Temp\digikam.txt
   set logging on
   set disable-address-randomization off
   run

After digikam crashes, do this:

   bt
   quit

Then attach your backtrace (the log file) to this bug report.

I used the official Windows installer from sourceforge
(digiKam-installer-2.5.0-win32.exe). It don't contents gdb, but i downloaded it
separately.

The line "set disable-address-randomization off" will cause the error "No
symbol table is loaded.  Use the "file" command.". Is this a problem?

When digiKam freezes, i have to kill it using the Windows Task-Manager. Before
it was not possible to type something into the gdb console. Then the command
"bt" says "No stack.".

I posted the gdb output anyway.

It does have it, but no matter. The one you downloaded should be fine.

No, it isn't a problem. The command just tells gdb to allow address
randomization so that if the crash occurs because of a race condition when not
debugging then it is more likely to crash while debugging (sometimes a crash
will not occur while debugging because gdb will turn off address randomization
so behavior will be different).

How long do you wait before you kill it? If digiKam actually crashed gdb would
inform you and then you can type 'bt'. If you can't type 'bt' then it hasn't
crashed yet and digiKam is simply waiting for something to happen, but it
hasn't crashed. If you kill it in the task manager, there is no stack because
the program is gone! You must wait until gdb informs you that there was a crash
(gdb will give a message like "Program received signal SIGSEGV, Segmentation
fault" or similar) and then you can type 'bt'. This could take quite a few
minutes.

Also, during all of this does your hard drive have high disk-activity? Does it
say "Scanning collection0%" at the bottom-left of digiKam's main window?

It will be fine to run debugview before to run digiKam:

http://technet.microsoft.com/en-us/sysinternals/bb896647

...and to see what's printed by application on the system console before to
crash.

To check the questions and use debugview, I do new tests. At the first test,
digiKam don't freeze! And I don't know why, I have change nothing. But at the
second test, all was like before.

> How long do you wait before you kill it?
A few minutes at the old test.
30 Minutes at the second test. But then I press Ctrl + C at the gdb console and
can type "bt" (and "quit"). The output:

[New Thread 412.0x16a8]

Program received signal SIGINT, Interrupt.
[Switching to Thread 412.0x16a8]

A debugging session is active.

    Inferior 1 [process 412] will be killed.

Quit anyway? (y or n)



> Also, during all of this does your hard drive have high disk-activity?
No.

No.



debugview shows no new entries after digiKam was started. Do you want the
complete log file anyway?

To see digiKam trace from debugview, run kdebugdialog and turn on digiKam debug
space.

digiKam is activated in the kdebugdialog. And debugview has traced some events.
But nothing after the start of digiKam was finished.
Or what do you mean?
