libruby1.8 breaks raggle?

[Michael Ablassmeier <abi@grinser.de>]

hi debian-ruby,

im the maintainer of "raggle", an rss feed aggregator written in ruby. It seems
like the update from libruby1.8(-1) to (-2) breaks it. Im not sure if its raggles
or libruby's fault, so i want your opinion first, before i open a bug against one
of these packages.

If rebuilding ruby1.8 (-2) without 101_cvs_updates.patch, raggle works nicely,
if the patch is applied it stops updating the feeds with:
    
 Feed Thread Reap Error: "temporal locking already locked string".

if running ruby in debug mode, following appears:

   Exception `RuntimeError' at /usr/bin/raggle:3611 - temporal locking already locked string
   /usr/bin/raggle:3611:in `write': temporal locking already locked string
   (RuntimeError)
       from /usr/bin/raggle:3611:in `puts'
       from /usr/bin/raggle:3611:in `main'
       from /usr/bin/raggle:4278

i already contacted raggle's upstream author, he trys to figure out whats going on.
Any ideas? (ive never seen that error before)    
 
bye,
    - michael
