Bug ID: 446258
Summary: KPA git master crashes in viewer - only on one PC &
user, not on the other ...
Product: kphotoalbum
Version: GIT master
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Viewer
Assignee: kpab...@willden.org
Reporter: schleth...@web.de
Target Milestone: ---
SUMMARY
KPA crashes always at a certain image while browsing images in full screen
viewer. Only on my wifes PC and only with her user, not as me and not on my PC
as any of us.
We access the album via NFS, files (except .thumbnails) are rw-rw-r-- - so we
both may write and edit the tags but only I may (re-)create thumbnails.
Both systems run Leap 15.3 with the same patch status and more or less the same
software spectrum.
Both systems run the same KPA release but each one compiled on the respective
machine.
STEPS TO REPRODUCE
This is a bad one : I cannot (yet?) reproduce the bug on my PC with my user or
with my wife's :-(
1. Open KPA
2. Select 2021
3. View Thumbnails
4. doubleclick on some image from spring
5. start browsing using the mouse wheel or page-down key
6. zap! Always while hitting the same image
... but I have a backtrace and the error message from the command line:
beate@wshome2:~> kphotoalbum -c ../usr/share/fotos/index.xml

KCrash: Application 'kphotoalbum' crashing...
KCrash: Attempting to start /usr/lib64/libexec/drkonqi
(The cpp-file looks innocent enough, only what in the world was it saving?)

... wait a minute: do I read something about background job and videothumbnails
???
All thumbnails are there, no need to (re-)create them. Also KPA has no business
to save any image file at that point.
I have set the two thumbnail folders to rw-r--r-- to be writable only by me as
I do not want all the thumbnails be messed up by any accidental interaction.
But this should pose the same kind of problems on both PCs when we access the
album with my wife's user (who has read only access to the thumbnails).
I also copied the images that crashed KPA to a different folder, created a new
album there and ... nothing. So it is not a problem of the respective images.
