Comment 1 Svata Dedic 2001-03-06 16:36:19 UTC 
I'm working on my part of the problem - findRelativeName is buggy. Should be corrected within one hour.
However, WHY is the debugger forcing parsing from the main thread and blocks until it gets the result ?
Comment 2 Svata Dedic 2001-03-06 17:03:24 UTC 
Fixed for dev-139.
Comment 3 Quality Engineering 2003-07-01 13:17:41 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
