kdenlive, shotcut both crash in dlopen()

After not having used it a long time, I decided it's time to do some video editing. Kdenlive however doesn't seem to work anymore on my system. Whenever it tries to show anything in the preview window (clip, title,still) it segfaults with

#0  0x00007ffff7de596c in _dl_relocate_object () at /lib64/ld-linux-x86-64.so.2

Interestingly, shotcut (from AUR) exhibits a similar symptom. I tried it since it also uses [mlt] underneath. It crashes slightly differently, but directly on startup:

#0  0x00007ffff7de596c in _dl_relocate_object () at /lib64/ld-linux-x86-64.so.2

#15 0x00007fffefe0354f in clone () at /usr/lib/libc.so.6

It seems that [mlt] may be the common factor, but I can't seem to find why it crashes for me. [mlt] itself doesn't do any QLibrary() calls.

Everything on my system is fully upgraded. I got rid of anything from AUR that may be related to this.

Re: kdenlive, shotcut both crash in dlopen()

stracing one to see what is supposed to be dlopen'ed might provide further hints on the cause.
