Also happens with Chromium but not with Falkon, so maybe we can generalize it to gtk apps?
Sadly Arch does not provide symbols and the backtrace is useless without symbols. Can you get symbols, reproduce the crash, and attach a symbolicated backtrace? See https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces

What packages exactly do I need to rebuild? I would guess baloo, but what else?
The crash is somewhere in liblmdb.so, so also whatever package provides the LMDB library.
Never mind, found the original. *** This bug has been marked as a duplicate of bug 353483 ***
