Comment 1 Vishesh Handa 2013-05-28 15:00:14 UTC
Thanks for the bug report. I have a feeling that this has been fixed, but I cannot be sure without the full debugging symbols.

Could you please install the debug symbols for Soprano. I'm marking this as RESOLVED - BACKTRACE till then. If the crash happens again, please feel free to reopen this bug or report a new crash.
