Exporting images to jpg fails regularly when using the equalizer plug. After disabling I am able to export to jpg. Failing images get "rendered" partly or not at all, as can be seen here:

This looks as if darktable ran out of memory while exporting. Do you use a 32bit system? How much main memory does your computer have? You can try to decrease the memory size in the preferences (and restart darktable).

It is a 32 bit system, with 4GB of memory. I'll try your suggustion and report back here.

After limiting the host memory for tiling down to 1024 (from the default 1500) the exports worked ok. Thank for the tip. An errormessage about running out of memory would be nice though... but i'm sure that'll happen sometime in the future

closing this as "invalid", not a bug.
A message would be nice, indeed...
