Steps to Reproduce: 1) Start thunar. 2) Wait. No specific action is required for thunar to crash. I just have to wait a few minutes and thunar crashes. Output in console says "Segmentation fault (core dumped)", there is no core file though. Executing generate-core-file in gdb outputs "Couldn't get registers: No such process." Output of "bt full" in gdb: #0 0x00007ffff4bca887 in g_slice_alloc () from /usr/lib/libglib-2.0.so.0 No symbol table info available. #1 0x00007ffff4bcad5e in g_slice_alloc0 () from /usr/lib/libglib-2.0.so.0 No symbol table info available. #2 0x00007ffff4bad244 in g_source_new () from /usr/lib/libglib-2.0.so.0 No symbol table info available. #3 0x00007ffff4bb00a9 in g_timeout_source_new () from /usr/lib/libglib-2.0.so.0 No symbol table info available. #4 0x00007ffff510a4c2 in ??

Thunar version 1.6.3git-fc4a4b6 crashes as well.

However, you seem to be the only person who can reproduce it reliably. It is crashing inside the glib memory allocator which indicates random memory corruption in a totally different part of the code, and seems to give many different types of crash. Please install debugging symbols for glib and gtk to get the missing symbols filled in, then redo the stack trace. Then please run it in valgrind like this: G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind -v --tool=memcheck --num-callers=40 --track-origins=yes --log-file=valgrind.log thunar And then attach valgrind.log. It will run really slow, don't worry about that.

Are you leaving it open on a directory where the files are constantly changing? strace may also be useful, to see what activity it is doing leading up to the crash.

Everything necessary should be in there. GDB log created with "gdb thunar", in gdb console "r". I ran valgrind just the way you told me to. Crash is a segmentation fault. That's it, or did I miss something?

Everything is consistent with memory corruption caused by mismatch between memory allocators - forcing it to always use malloc prevents the crash. But your last log crashes while allocating. G_SLICE=debug-blocks should cause a crash on deallocation.
