Problem with object sender in -insertTab:

[Germán Arias]

Hi,

In Gemas app, I overrides the method -insertTab: to do some indent operations. 
I call the method -tag in sender object to know if the user want insert a real 
TAB. This worked perfectly until some days ago. But suddenly, call any method 
in sender object crash the app. According with GDB the sender object exist. So, 
I don't understand what is happening. I can change the code to not call methods 
in sender objects. But I think this is a bug on GNUstep.

Any advice?

Germán.
