[Bug 2120477] Re: speech-dispatcher crashed with SIGSEGV in start_thread()

 

Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed as the report has a core dump which is invalid. The
corruption may have happened on the system which the crash occurred or during
transit.

Thank you for your understanding, and sorry for the inconvenience!


** Changed in: speech-dispatcher (Ubuntu)
