Getting `kf.windowsystem: Cannot use KWindowSystem without a QGuiApplication` with SVN

Help
1

So I’m getting kf.windowsystem: Cannot use KWindowSystem without a QGuiApplication message whenever I try and use svn command. From bash, it still ends up working fine, but from within IntelliJ, it causes a problem and stops whatever action I’m trying to perform from occurring. Even just listing branches to check one out. Running Debian 12.1, pretty new install, up to date.

there was a bug resulting in the same message because of kwallet not running, but it was fixed in svn 1.12.something, and I have kwallet running, so should be something else…

4

My SVN is 1.14.2, so not sure what else it could be

5

bump anyone have any clue?

6

Do you have an SSH key set up and the “ksshaskpass” program installed?

7

No SSH key, and this is work, and can’t really get one setup.

And ksshaskpass is already installed.

8

If you uninstall ksshaskpass, does the issue go away?

9

Nope, didn’t change anything.

$ sudo apt remove ksshaskpass

Hi all, I am seeing this issue on version 1.14.3 (and Kubuntu 24.04). Has anyone been able to find the cause of this error?

$ svn --version
svn, version 1.14.3 (r1914484)

Maybe I can bring some light into the problem/mystery:

In the default config, SVN probes for the available password store. I assume it first requests the GNOME Keyring before KWallet is tested.

I had switched off the Secret Service support in KWallet in preparation to use another program for this service, and SVN began throwing this “funny” error message.

Here are the step-by-step instructions to “fix” the issue:

  1. Remove existing entries for Subversion in the KWallet.
  2. Switch on the Secret Service.
  3. Reboot (I made one, don’t know the necessity).
  4. Let the Secret Service collect the credentials.

Alternatively, configure the keys “password-stores=kwallet” and “kwallet-wallet=…” in ~/.subversion/config. Use the last one only if you want a different wallet than the default.

Hope this helps. Have a nice Xmas.

Cheers.
