[TxMt] Code-completion issues with Objective-C

Having problems with code-completion in Objective-C.

Basically, whenever I hit alt-escape for triggering a completion I get this:

sh: : command not found /tmp/temp_textmate.I8XxsT:164:in /bin/bash: -c: line 0: unexpected EOF while looking for matching `'' /bin/bash: -c: line 2: syntax error: unexpected end of fileshow_dialog' from /tmp/temp_textmate.I8XxsT:118:in /bin/bash: -c: line 0: unexpected EOF while looking for matching `'' /bin/bash: -c: line 2: syntax error: unexpected end of fileprint' from /tmp/temp_textmate.I8XxsT:488

I am not sure, but I feel like I have seen errors like these pop up in other bundles as well. Any clues? Thank you.
