Sentry Crash Report:

Description Henri K 2023-10-12 15:27:45 UTC 
Updating *session* index for any directory causes error:

[CTags Error] Failed to run. Error: execvp: No such file or directory, exit code: 255.

Adding same directories to *common* index from Settings -> Ctags and updating works fine. "/home/henri/.local/share/kate/katectags/common_db" is created and for example "Go to local symbol" works.

STEPS TO REPRODUCE
1. Install (universal) ctags
2. Enable Ctags plugin
3. Open Ctags session index from bottom panel's Ctags -tab.
4. Under "Index target" click "+ Add"
5. Choose any directory
6. Click "Update index"

OBSERVED RESULT

Error: [CTags Error] Failed to run. Error: execvp: No such file or directory, exit code: 255.

EXPECTED RESULT

Shouldn't get error and indexing should work.
