Further attempts result in the same behavior.

Comment 1 caulier.gilles 2009-05-23 23:30:56 UTC

gdb backtrace is not suitable. Are you installed digikam-debug package or compiled digiKam with full debug info (loook README fr details)

Anyway, with current code from svn (0.11.0), i have fixed some crash relevant of video thumbs get for camera.

Comment 2 tv.debian 2009-05-24 00:05:46 UTC

I'm installing digikam-dbg, and I'll try to reproduce the crash then.

I've noted that everything is going well if I mount the camera as an external drive in Dolphin, prior to opening Digikam pictures-import gui. If I go directly for "Import images with Digikam" in the external media dialog I get the crash.

I'll try newer version as soon as it's available in Debian experimental or Unstable, I don't have time to build it now...

Thanks for you attention, and your work.

Comment 3 Andi Clemens 2009-10-01 16:15:42 UTC

Any updates here? Debian unstable should have new packages by now.

Comment 4 tv.debian 2009-10-01 18:24:50 UTC

Hi, the camera Panasonic (Lumix) dmc-tz5 is only episodically available to me, I had the opportunity to use it this week twice, and everything went well.
I am now running Digikam 2:1.0.0~beta4-2 from Debian "testing" ("Squeeze"), on KDE4.3.1. So regarding Digikam the crashes seem to be gone, issue solved.
Now let's find why the device-manager applet isn't unmounting cleanly mass-storage style cameras... But that's another story ;-)

Thanks for your work.
