Title:
  Hugin crashes on opening pto file (OS X)

Status in Hugin - Panorama Tools GUI:
  Fix Released

Bug description:
  
  Hugin crashes from time to time on opening a pto file. It seems to hapen more often when other programs are open in the background.
  The same pto file can open 10 times without a problem and then 4 times cause Hugin to crash.

  Hugin 2011.4.0 (Mac)
  OS X 10.6.8
  iMac7,1, Intel Core 2 Duo, 2.4 GHz, 4 GB
  Activity monitor: page-outs: 0 bytes, free memory 1.95 GB
  pto file with 2 or 4 TIFF images, 16 bit gray, 717 x 2706, 3.9 MB

  
  Exception Type:  EXC_CRASH (SIGABRT)
  Exception Codes: 0x0000000000000000, 0x0000000000000000
