Anybody experiencing 'yelp' instability?

["Martin S. Weber" <Ephaeton%gmx.net@localhost>]

..as for me it keeps dying on 4.99.72/i386 with the below stacktraces...
(1st is from starting yelp directly I think and 2nd from within gnucash).

 - plain -current, 1 to 2 weeks old yelp and gnucash packages,
   I even didn't modify mk.conf except default options -inet6,
   running on a non-ipv6 kernel and built with mkhtml=no.

What I do to provoke this is:

- start yelp. Wait.
- start gnucash, click help -> tutorial. Wait.

"application bug" once more? Or might this even be some threading issue?

Anybody seen else something like that?
