[ubuntu-mono] [Bug 1351360] Re: f-spot crashes (segfault) when any Export method is chosen

[Florian Quèze]

If I start f-spot from a terminal, at the time of the crash I see this
error message in the terminal:

Title:
  f-spot crashes (segfault) when any Export method is chosen

Status in “f-spot” package in Ubuntu:
  Confirmed

Bug description:
  When exporting any photo or group of photos by any enabled method
  f-spot reproducibly suffers a segfault and crashes.

  This appears to be a duplicate of bug #1269760

  Here's some output from strace around the time it happens:

  This is not specific to the Zip file export; any export option (such
  as "Export to folder") behaves the same way.
