Failed to launch GDB: No such file or directory

I have been looking for this error on the Internet and in some forums I have found the possible cause of this 
failure. According to what they mention, the problem is in the output length of the plugin, crashing when the
length is greater than 4223 bytes.

It looks that this bug have been fixed for Ubuntu distributions, but not for Debian. 

Please, solve this issue.
