            Bug ID: 335642
           Summary: KMail freezes when loading folders
    Classification: Unclassified
           Product: kmail2
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: afiestas at kde.org

I guess this is an error in akonadi libs but it might be KMail doing an async
use of them as well...

These are some backtraces of a gdb attached to a KMail with a complete frozen
GUI.
