Description Dinescu Stefan 2018-01-29 13:02:32 UTC

Trying to open a file in an external editor by using "Open With" dialog, with "Remember application association" checked, will never finish and if the user chooses to cancel the action, the application will crash.

Steps to reproduce: 
1. Open any file inside Kate
2. Access "Open With" dialog, either by File/Open With, or by right clicking on a document inside "Documents" plugin
3. Check the "Remember application association" box
4. Click OK; a dialog "Updating system configuration..." appears and will never complete
5. Press Cancel in the "Updating system configuration..." dialog

Comment 3 Dominik Haumann 2018-02-04 20:56:45 UTC

Bug #356506 is probably a duplicate of this report from year 2015.

I can reproduce the crash under Linux, btw...

Comment 4 Dominik Haumann 2018-02-04 21:02:21 UTC

@dfaure: Can you see anything useful in the backtrace in kio?

This is most likely a bug that is very old.
