It looks like the stack in bug 204781 (fixed 2003) matches this one...

The crash is quite random and have only managed to reproduced in on this
intranet site.. got it to crash again to day with TB3301342W on the
20050123-trunkbuild.

Think I managed to recreate problem on a normal "internet site",
http://www.amv.se/rdfs.asp?L=29
and clicking on the left hand frame link called "Platsbanken" before the full
frame was loaded.
TB3322628K was created.

Actually found another bug which acatually matches my problem. Tried the latest
trunk and WFM now. Resolving myself.
