 error in process sentinel with Melpa added to package-archives

[Message part 1 (text/plain, inline)]
Looks like, some minor mode keeps on checking for balanced parentheses and
throws errors as I type "(require 'package)" after "r -Q" in gdb.

Is that expected? If so, what do you need to disable to prevent these false
breakpoints?

Thanks.

Here's a backtrace for that:
