Description Daniel Tang 2020-04-27 23:43:22 UTC

SUMMARY

After a while I stop being able to open Konsole with the keyboard.

STEPS TO REPRODUCE

1. Spend an hour doing something like using Android Studio
2. Try one of the following:
   - Press SHIFT + F4 in Dolphin
   - Press CTRL + ALT + T anywhere (make sure it's set as a custom shortcut)
3. Try one of the following
   - Press F4 in Dolphin
   - Open Konsole from the start menu
   - Open another Konsole window by typing "konsole" in Bash

OBSERVED RESULT

None of the things in Step 2 work. They are silently ignored. All of the things in step 3 work.

I can get "CTRL + ALT + T" to work if I "kquitapp5 kded5" and "kstart5 kded5". I can't get "SHIFT + F4" until I log out and log back in. Both the "CTRL + ALT + T" and "SHIFT + F4" seem to stop working at the same time.

EXPECTED RESULT

To be always able to open Konsole.

That is, for the things in step 2 to always work just as well as the things in step 3.

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: Ubuntu 20.04
KDE Plasma Version: 5.18.4
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8

ADDITIONAL INFORMATION

This started happening in April 2020 (but I also started using Android Studio at that time).

Thanks for the report Daniel, I am unable to reproduce this issue on KDE Neon with the latest Konsole from git master.

Can you please retest and confirm this is still an issue, thanks.

This bug hasn't occurred to me since.
But again, I haven't being using Android Studio much either.

I've thought about this, and it seems like the problem is with DBus as I remember seeing a kglobalaccel5 crash and having DBus problems right before this issue started happening.
I think the problem might be because DBus enters an error state and my environment variables are still pointing to that errored DBus.
Konsole might be trying to do something with DBus on startup, and ends up waiting forever.

I haven't had any Konsole, kglobalaccel5, or DBus problems since and my system has been stable for months, so I think some bug has been fixed somewhere
