[Mats (matsben)]

It is clear it is the parsing of the history file that bails for some
reason. If you have any clue of which user you were chatting with before,
and are willing to share it, you can mail me directly at <email address hidden>.
Else just delete that file, or the complete history in the prefs folder:
Coccinella/History/ Since history parsing has never failed for me it is hard
to debug this problem.

[sander (s-devrieze)]

The problem is I can't reproduce this error...

[Mats (matsben)]

The lines:
can't read "xmlobj(9)": no such element in array
...
"::tinydom::XmlElementEnd log -namespace jabber:x:event"

indicates something being wrong since normally an element (composing) should
appear at level 4 or something, not 9. Either the history file is corrupt
somehow, or there is some kind of reentrance problem in my tinydom code.

I have now rewritten tinydom to be completely safe from any reentrance
problems, although I'm not sure that is the problem.

[sander (s-devrieze)]

Let's close this bug entry then :-)
