Bug ID: 496512
Summary: crash on creating symbolic link from symbolic link to
*.svgz
Classification: Applications
Product: gwenview
Version: 23.08.5
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: private_l...@yahoo.com
Target Milestone: ---
SUMMARY
Creating a symbolic link to svgz in secondary folder from existing symbolic
link to svgz crashes gwenview
STEPS TO REPRODUCE
1. following file-system setup:
a: ~/pics/cat1/image.svgz
b: /tmp/folder-XYZ/image.svgz -> /home/user/pics/cat1/image.svgz
c: ~/pics/cat2/image.svgz -> /home/user/pics/cat1/image.svgz
d: ~/pics/summary/cat2/ -> /home/user/pics/cat2
e: ~/pics/cat3/
f: ~/pics/summary/cat3/ -> /home/user/pics/cat3
2. open b: directly in a fresh gwenview process (e.g. navigate to it with
gwenview 1 and select the "open new window" command to launch fresh gwenview 2
- this process will crash)
3. open the symbolic link to the image in d: (e.g. Ctrl+O)
4. this step is a little blurry in my memory - I closed the single image-view
by ESC and fiddeled with the sort order to make it sort by date, as it always
starts with some random order (so cat2 actually contains around 300 links to
other pictures, mostly jpg though). Thereby the selected image moved off screen
and I pressed ENTER, to open it again and ESC to focus it in the list/to scroll
to it. I definitely didn't show any other picture in single picture view.
5. drag and drop the picture-link to f: a context menu appears
6. select either link or copy
OBSERVED RESULT
gwenview crashed
EXPECTED RESULT
new symbolic link is created in f: and ultimately in e:
