Crash upon reply w/format=flowed

[Albrecht =?iso-8859-15?Q?Dre=DF?= <albrecht dress arcormail de>]

Hi all,

in my incoming mailbox, I have exactly one mail which makes balsa (today's 
cvs version plus some older ones) crash when I try to reply to it with 
format=flowed checked. Reply without format=flowed works fine. I tried to 
find the reason using the debugger, but everything looks fine to me. 
Therefore, I attach the "bad message" (all relevant information 
overwritten...), and hope that someone can help me with that. System details 
are ---

* balsa from today's cvs
* LinuxPPC system w/ glibc 2.1.3, gtk 1.2.8, gnome 1.2.13

I attach the GDB output below. The strange thing is that the backtrace says 
process_mime_part was called with a NULL body (#3). It was *not*. Also, 
gfree() (#2) was not called with a NULL argument. So I assume that somewhere 
something nasty goes on, maybe freeing the string in process_mime_part?

Thanks in advance,

         Albrecht.
