marcof,

Do you think it looks like this one:

http://www.amule.org/amule/thread.php?threadid=4575&sid=

:D

I'm looking at it, but I still don't know how m_reqfile became NULL (DownloadClient.cpp, line 263). It was certainly not NULL before line 217 executed, otherwise m_reqfile->GetFileHash() would segfault. If you find the place where m_reqfile becomes NULL, please tell me :)

Cheers!
