Tab

DESCRIPTION
The editor tab works correctly even with enormous (260 000 entries!) PO files.
Trying to access the PO entries from the TM Tab does not work for large files
like this, resulting in a crash probably from an integer overflow.
STEPS TO REPRODUCE
1. Turn a ~40MB PO file into a TM database (I don't know at what size the
indexing error starts to occur, but it appears with my 40MB file)
2. Search for anything (even empty string) in the TM Tab, searching the large
database
3. Open a result in the editor tab, by clicking on a result in the database
entries list (I think the actual entry index in the PO file was ~220 so the
index of the translation unit itself is probably not the issue)
OBSERVED RESULT
Probably an integer overflow, judging by the printout below:
