[Bug 210424] New: Occasional crash on startup

https://bugs.kde.org/show_bug.cgi?id=210424

           Summary: Occasional crash on startup
           Product: digikam
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:            (using KDE 4.2.4)
Compiler:          gcc 4.4.1
OS:                Linux
Installed from:    SuSE RPMs

Digikam compiled from recent trunk (rev 1033809) crashes occasional during
startup. It does not happen every time, maybe one out of four. I haven't been
able to notice any consistent thing that would trigger the crash (after crash,
next time it may startup normally, or then it may crash again).

Unfortunately I haven't been able to cause the crash when running Digikam in
gdb, so I cannot provide a gdb stack trace. I'll include output of Digikam
before the crash and info provided by the KDE crash handler.

Since this happens only occasionally, my guess would be a concurrency and
timing related problem? (I have a dual-core processor, and hardware concurrency
has a tendency to show these bugs more easily.)

To me it looks like a Kipi-plugins related issue (jpeg loseless). The backtrace
could be related to the one in https://bugs.kde.org/show_bug.cgi?id=200159#c12

If you can reproduce the crash at will (or you experience this regularly), can
you install the "kipi-plugins-debuginfo" package and post a complete backtrace
here? Thanks

Also ensure that you updated to a recent version of libkipi and kipi-plugins.
Maybe some binary incompatibility.

Hmmm... Marchel, you may have something there.

I compile libkipi and kipi-plugins from svn.

However, on my KDE 4.2.4 machine, Digikam's cmake does not find necessary
libraries to compile calendar kipi-plugin (is some extra configuration needed,
I think I should have all necessary lib and devel packages installed?). So,
Digikam build is configured not to compile the calendar plugin.

Now it seems that when I run Digikam, it still tries to load the calendar
plugin and find the KDE 4.2.4 version. I'm not sure if that might be the reason
for my problems.

Or maybe I'm configuring something wrong in the build process, digikam.org's
compilation pages (http://www.digikam.org/drupal/download?q=download/KDE4) are
not very complete in this respect, I think. Especially if and when I want to
install Digikam and necessary libraries somewhere else than /usr/lib (I
wouldn't like to put development stuff from svn there).

Matti,

remove your CMakeCache.txt file from your root source code dir, and start cmake
again...

Nicolas,

I had complete forgotten this bug report. It can be closed, I managed to get
rid of the problem with help from Marcel. I had installed Digikam to a
non-default location and apparently it managed to find a couple of old
kipi-plugins from elsewhere in the system.
