It seems recent google play version brakes this rom
All worked fine until these days. Now, sometimes trebuchet crashes in fast loop. When it happens, the device is unusable. The boot is very slow because theses crashes, if you wait few minutes, the crashes loop stops without apparent reason and you can use the device. I have attached crashes files to my message.
Other cyanogenmod users are affected, see here :

[EDIT]
I found out the root cause, google play service is not the issue :

It means I can't update no more my device
thanks google
