Help camera does'nt work in other apps

[vladkeel]

Hey guys,
Just got my hands on a Defy Plus, it's running CyanogenMod 9.
Now, the camera on it self is working fine, that is with the app it came with.
Other apps like instagram and camscanner work fine too,
But most apps i try to run, that need a cam (barcode scanners, joke photo makers etc.) just show a blank black screen instead of cam image.

This feels to me like a permissions issue, but being new to this whole smartphone thing, i wouldn't know where to start.

Any insights?

Thanks.
