Description Marek 2016-08-06 12:52:16 UTC

When I upgraded from 5.6.4 to 5.7.2, the desktop became unresponsive (no menu on right-click, panel didn't react to left- or right-click, desktop shortcuts didn't work). I couldn't even log out, and had to kill the session (ctrl+alt+backspace). I created a new user and  tracked the issue down to a .desktop file referring to a .svgz icon. When I removed the offending file, the problem went away.

I had this .desktop file for some time and it worked without issues with 5.6.4 (and probably for some time before).

Reproducible: Always

Steps to Reproduce:
1. Create a test user 'tester' and login into plasma shell. All works as expected. (on Fedora, default desktop type is "Folder View")
2. Copy the .svgz file to /tmp 
3. Copy the .desktop file to /home/tester/Desktop/

Actual Results:  
The desktop becomes unresponsive.

Expected Results:  
It should not happen; if svgz is no longer supported the icon should just become a "generic icon" instead of freezing the desktop.

Comment 3 Kai Uwe Broulik 2016-08-10 07:57:19 UTC

Can you get a backtrace of plasmashell, perhaps? What KDE Frameworks version is this?

Comment 7 Marek 2018-09-28 13:38:25 UTC

I provided the information two years ago.

Comment 8 David Edmundson 2019-10-15 19:49:27 UTC

Can you reopen if this is still an issue? We haven't had any other reports.

I could not reproduce.

Note also the file attached is not a compressed .svg the contents are plain text.
Yet the file format is svgz and the backtrace shows we're decompressing things. That could be an issue attaching or could have been the source of the original problem.
