I think the problem is that xsane does signal handling the wrong way, and the crash is a result of the signal handler being called for a second time while the first invocation is not yet done. I have a patch that fixes this, it basically splits the signal handler in two parts, the "top half" just writes a character into a pipe when a signal arrives, this gets picked up by the "bottom half" which is services through the normal event loop (and therefore may call non-reentrant functions and so forth).
