Noticed same problem with CVS version 20071106 on KUbuntu 7.10, wxWidgets 2.8.6
I will re-build aMule with debug options to get more info.
I was forgetting; I don't know if this can be useful: I'm sure that a lot of file were "in hashing" (I started aMule with about 350 files to hash and when I re-started aMule this morning after the crash I noticed about 10 files remaining to hash)
Bye,
Mr Hyde
