Comment (by o_sukhodolsky):

 Replying to [comment:53 rlaager]:
 > I'm noticing 2 blank lines showing up at the end, in the log viewer,
 now. I added a g_strchomp(), but can we avoid having to do that?

 one possible cause of this problem could be condition for "while(c)",
 perhaps replacing it with
 "while (c && *c)" will help.  But for me it is hard to say this for sure
 since I do not have any trillian log to test with  (all my changes I've
 tested with some handwritten files :(  If you would
 give me some log for testing I'd try to find the cause and the fix.
