Comment 1 Lasse Liehu 2015-11-23 19:44:25 UTC

Noticed that there is no crash when the file exists. When I was able to reproduce this crash, I always clicked on the same suggestion and it was from a file that no longer existed.

Comment 2 Lasse Liehu 2015-11-23 19:57:04 UTC

Also noticed that the same crash seems to occur when clicking a search result in Translation Memory tab.

Comment 3 Nick Shaforostoff 2015-11-29 22:52:41 UTC

this is very strange. when i rename the file that would be opened by "Open file containing this entry" this entry just doesn't show up (only "remove this entry" is there)

Comment 4 Lasse Liehu 2015-12-04 19:15:58 UTC

I was actually wrong that the file didn't exist. I just didn't see it on the project overview. Anyway, opening that po file crashes Lokalize every time. Attaching it.
