>Description:
	I'm no expert in debugging things, sorry..

	
	I don't know exactly what happened, but I think this happened after the
	package had been partially removed, which iirc had failed, although
	this is sheer speculation.
	Please let me know whether you need additional information/files and
	SSH access if you think it helps.
	The package I tried to delete was gtk+2 in an attempt to perform an
	update.

	If I knew exactly how I did this...

 This sounds like the classic corrupted bdb file issue. There are some
 band aids in various parts in place to reduce the chance of crashing,
 but they are not perfect. Try running "pkg_admin rebuild" first.

 pkg_admin rebuild did the trick, but it shouldn't segfault, no?

 No, it shouldn't. (Nor should the files get corrupted, either, but
 with db-1.85 there are some effectively unfixable ways for that to
 happen.)
