            Bug ID: 407271
           Summary: KAboutData crashes when using git svn with KWallet
           Product: frameworks-kcoreaddons
           Version: 5.57.0
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: mp...@kde.org

Backtrace

Running "git svn rebase" crashes reproducibly with the following error message
when using kwallet as an authentication backend:

$ git svn rebase
org.kde.kwindowsystem: Could not find any platform plugin
Current branch master is up to date.
error: git-svn died of signal 11

The command is executed properly and commits are also added to the local git
clone.
But when cleaning up afterwards the git-svn script produces a segfault.


STEPS TO REPRODUCE
1. Clone a git repository from an SVN server and set kwallet as password
storage backed.
2. Run "git svn rebase"
3. Observe the crash 

OBSERVED RESULT
Calling "git svn rebase" will now always generate a segfault:
