BUG in 2.3.0: balsa hangs and destroys mbox file

[Albrecht Dreß <albrecht dress arcor de>]

Hi,

I tried to clean up my (rather large) incoming mbox file using balsa 
(CVS ChangeLog rev. 1.2005). The inbox is configured to erase deleted 
messages immediately. After erasing several messages, balsa hung with 
zero cpu load.

I attached gdb to it, which said

<gdb>
Program received signal SIGINT, Interrupt.
[Switching to Thread 805576032 (LWP 3157)]
0x0e690264 in pthread_cond_wait@@GLIBC_2.3.2 () from 
/lib/tls/libpthread.so.0
(gdb) bt full
#0  0x0e690264 in pthread_cond_wait@@GLIBC_2.3.2 () from

[rest of the bt snipped]
</gdb>

Killed the process, and now the mbox file is partly destroyed: the 
beginning is still intact, approximately at the point where I tried to 
erase the last message, ALL mails of a ~ three month period (!!!) are 
gone, and at the end about 5 new ones are still there.

ARRRRGH!!!!!!

Although I was able to restore some parts of that file from a backup, 
more that three weeks of mostly very personal messages are lost. I think 
I don't need to say that this behaviour is *completely* inacceptable.

Any ideas?

Cheers, Albrecht.
