While trying to render some scenes with Cycles, I have been getting a crash with segmentation fault as a reason while having GPU and CPU hybrid rendering active. In many cases the problem is solved by choosing CPU in the device type and then rendering.
Terminal message:
TIFFReadDirectory: Warning, Unknown field with tag 37724 (0x935c) encountered.

System options have the GTX 970 and CPU as compute devices, Cycles has GPU rendering active. Sample file may have CPU selected.
28Jem_rebuild_example.blend
Based on the default startup or an attached .blend file (as simple as possible).

I sadly do not have a CPU+GPU combo setup to test this.
Could you try a newer build in the off chance that this has been solved?

Changed status from 'Open' to: 'Resolved'
This was a temporary issue in the first beta build, it's been fixed since then.
