Bug#514913: digikam: crashes in image restoration tool

[Wolfram Quester-2]

Package: digikam
Version: 2:0.9.5~beta3-1
Severity: normal


Hi altogether!

I can crash digikam in the image restoration tool reproducibly if I abort the
restoration process during preview. To reproduce this, do the following:
- in digikam, select an image,
- click the edit symbol in the toolbar
- open the restoration tool via Enhance -> Restoration
- while the restoration tool loads the first preview, click on the
  stop sign directly right to the progress bar while it shows restoration: ..%
- the process stops, all seems normal
- click the Try button and wait a few seconds until the KDE crash handler opens.
  After I installed digikam-dbg, the crash handler is still unable to create a
  backtrace and says:
  > This backtrace appears to be of no use.  This is probably because your
  > packages are built in a way which prevents creation of proper backtraces, or
  > the stack frame was seriously corrupted in the crash.

  One time the attached backtrace could be obtained.

I use digikam with XFCE as desktop environment.
For me this looks as if in this case a pointer is not properly freed and
reassigned after the Try button is pressed. Perhaps a temporary memory area
which shall contain the preview is freed and then nonetheless reused.

With best wishes,

Wolfi

Well, I can still crash digikam. Well, not exactly crash, but the windows
of digikam and the editor freeze. I have to kill it and restart :-(
But the bug does not seem to be as easily reproducible as the one I reported
initially.
I think this bug can be closed since main development now goes to 0.10.x
anyways. I'll try and report back on success and failure when installed that
;-)

Hapy easter,
