https://bugs.kde.org/show_bug.cgi?id=304952 Bug ID: 304952
Severity: crash
Version: 2.8.0
Priority: NOR
Assignee:

Summary: Digikam thumbnails don't load, even after rebuild
thumbnails | application crashes
Classification: Unclassified
OS: Linux
Reporter:
[hidden email]
Hardware: Ubuntu Packages
Status: UNCONFIRMED
Component: general
Product: digikam
Application: digikam (2.8.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Linux Mint 13 Maya
-- Information about the crash:
Go to Tools → Maintenance → and check [✔] Rebuild Thumbnails. Click [OK].
Most times Digikam freezes, but this last time it crashed (I guess that's
good).
Before it crashes, the thumbnails aren't visible. The thumbnail file format is
Nikon's NEF raw image format, though other file formats don's show up, either.
When clicking on an image, the image shows up just fine in the preview.
THIS MIGHT BE A RELATED BUG:
Right click on an image preview and go into Edit mode. Edit the image. Go to
File → Save As New Version → PNG. The edit window will hang indefinitely after
saving 100%. After killing the application and restarting, I find that the new
version of the image was saved.
-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
