I couldn't find the problem with that regex exactly, but it seems to be 
the [^\"]+ part.

This seems to work here:
File\s(\S+?), line (\d+)|(\S+):(\S+):

It might need tweaking though. The regex doesn't have to match the 
entire line.

Also, the 2nd regex seems to be unnecessary as Geany already tries this 
pattern as a built in.

No, the type two matches start from 1.
