Good point, but it can't be quite a correct match or it would have
worked for Laszlo.

No, matches are numbered in the order of their ( and don't change even
if the previous ones don't match because they were in a different
alternate branch.

The ( after File is 1, the ( after line is 2, the two ( in
:([^:]+):[^:]+:([^:]+)) are 3 and 4 so they would be ignored by geany
since we only look at one and two.
