            Bug ID: 350526
           Summary: KMail hangs on start in GrantleeThemeManager
           Product: kmail2
           Version: Git (master)
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: aspotashev at gmail.com

I'm not sure what has changed in my configuration, but KMail now hangs on
start. I used it successfully during the previous few days, and I did rebuild
KDE PIM in parts a few times, but I didn't update any parts of KDE PIM between
the last successful start and the first unsuccessful one.

Below is the backtrace when I stopped KMail in GDB a few seconds after start.
It always stops with this same call stack.
