#3680: frontend crashes with a SEGV watching an HD video
--------------------------------------------+-------------------------------
Reporter: Derek Atkins <warlord at mit.edu> | Owner: ijr
Type: defect | Status: new
Priority: minor | Milestone: unknown
Component: mythtv | Version: head
Severity: medium | Mlocked: 0
--------------------------------------------+-------------------------------
Using trunk/r13508 I get the following crash watching a recording of
Letterman from two nights ago. This crash happens every time at
approximately the same place in the video, so I can reliably reproduce
this crash. I can try updating to newer code?
Program received signal SIGSEGV, Segmentation fault.
