Comment 1 Benjamin Girault 2013-10-28 18:54:40 UTC 
This trace does not contain enough information to investigate, however, I'm pretty sure what is the problem.

Can you confirm that when opening the plugin with the files (by either selecting the files before starting the plugin, or passing them as arguments to the executable panoramagui) then the plugin doesn't crash?

If this is the case, it's already fixed in the repository.
Comment 2 Jekyll Wu 2013-10-29 02:23:32 UTC 
can confirm the crash doesn't happen when a file is given as argument.
Comment 3 Alexander 2013-10-29 14:39:41 UTC 
I also can confirm that it doesn't crash when a file is given as argument.
Comment 4 Benjamin Girault 2013-11-01 09:43:14 UTC 
The relevant commit is 3d1a27f97906dace0ef8ab33cf7642109088926a
