debuild fails if GREP_OPTIONS are set in environment

[Andreas Roth]

Binary package hint: devscripts

devscripts: version 2.10.61ubuntu5

On my PC i set the GREP_OPTIONS environment variable in .bashrc:
export GREP_OPTIONS='-Hn --color=auto'

When the GREP_OPTIONS are set, debuild will fails with the following line:
debuild: fatal error at line 643:
don't understand dpkg-parsechangelog output: (standard input):1:Source: pkgname

I recommend to reset all GREP environment variables to an emtpy string (default), to ensure that grep is working as expected within the devscripts.

This is probably the same bug as http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=501055. Are you running debuild with --preserve-env?

[Andreas Roth (aroth)]

You're right it is the same issue.
I run the debuild from the package directory which any arguments and debuild immediately terminates with the error (on ubuntu precise):
debuild: fatal error at line 640:
don't understand dpkg-parsechangelog output: (standard input):1:Source: pkgname

I noticed that the options '-Hn' to grep are the cause of the problem. Only using the '--color=auto' option does not hurt at all.

Thanks for confirming that it is the same bug! I have added a bug watch for the bug in Debian.

I committed the fix in the Debian git repository [1]. It will be fixed in the next upload.
