Mysterious crash

Hello, I just love using Scrivener, but for mysterious reasons it systematically crashes when I access the context menu. I tried both ctrl-clicking and double-finger-clicking on the trackpad: same effect. The same functions work perfectly when accessed from the main menu.

I have a MacBook Pro mid-2011, Yosemite as OS.

I understand I am probably the only person experiencing this problem, but is there a workaround? I would very much like to use to software at its fullest, since I bought it

Thanks,
Claudia

What does the crash report say, please?

And have you upgraded to Scrivener 2.6 yet? Earlier versions are not Yosemite-compatible.
