newest master: darktable-cltest crashes

Hi,

I just compiled with LMDE6 the newest master of darktable.
→ darktable 4.9.0+306~gc728e0314f

While darktable itself seems to work fine, darktable-cltest crashes with the following messages:

~/darktable$ darktable-cltest

Backtrace:

this is darktable 4.9.0+306~gc728e0314f reporting a segfault:

Not sure what is happening here…
Cheers, Martin

I think you should start a GitHub issue.
