ImpEx crashes while importing from Invision Board 2 (2.3.0)

Importing from Invision Board v 2.2.2
Installed add ons: blog, gallery, and arcade

Importing process crashes while importing Posts. Actually just one post causes the problem and of course i couldn't manage to determine which post.

Error message reads:
-------------------------

Apparently a problem with some regular expression emerges. I've tried putting try catch blog around the problematic 78th line but it did not work.

By the way I'm not trying to get a perfect importing process (that would be perfect though). I just want to circumvent the problem. If one can at least help me to determine which post causes the problem i can just delete that post. Because I'm doing this importing process in a limited time frame.

Thank you.
