Thu May 14 19:20:03 UTC 2009

Package: boinc-client
Version: 6.2.18-4
Severity: important

Hello,

I'm using Debian Squeeze (testing), and I think I'm having the same kind
of problem as described above. When I launch the daemon from command
line, I get these messages :

and the program hangs.

If I launch it with invoke-rc.d boinc-client start, the file
/var/lib/boinc-client/stderrdae.log contains :

Under GDB, the backtrace I've managed to retrieve doesn't seem very
helpful :

-------------------------------------------------------

I think this bug is similar to #404269, but as it is archived, I
have not been able to add any comment on that bug report.

I would be glad to do any test you may think of.
