Description M Johns 2019-02-07 08:06:01 UTC

SUMMARY

The right click menu on directories, and kdewallet password both show at once, and the app is completely locked up.

STEPS TO REPRODUCE
0. Configure kdesvn so it using kdewallet
1. start kdesvn
2. quickly choose a directory
3. quickly right click in the left pane
4. after the menu shows, the kdewallet modal dialog shows

You may need some latency on your network for this to happen (I am in NZ, where round-trip latencies are normally about 200ms).

OBSERVED RESULT

Both the menu and the kdewallet modal dialog are showing on screen at once.

The app "hangs".

EXPECTED RESULT

Maybe the kdewallet modal dialog should take precendence and close the popup menu,

Does this actually crash the application? If so, can you please provide a backtrace to make diagnosing the issue easier for the developers. Instructions on how to provide one are available here: https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Sorry, I don't have kdesvn installed any more, and I couldn't easily find a svn repository to test with.

Every time I have seen a similar problem in the past, it has been a race condition where two modals show at the same time but they are modally "deadlocking" each other (the app itself hasn't actually crashed or hung, but the UI is now locked up).

In this bug. two modals end up showing at the same time: both a menu on the main window and a modal dialog for the password. My belief is that neither the menu nor the modal password dialog is responsive because the one on top is modally locked by the one underneath.

You are welcome to close this bug if it can't easily be reproduced.
