"internal server error" when pylint is used

[Sergey Gerasimov <sergun@…>]

Bitten slave hangs up in "in-progress" state and produces "Internal server error" if I use pylint step.

OS: FreebBSD 8.0 Python: 2.6 Bitten: 0.7dev_r1004 TRAC: 0.12.2 pylint: 0.21.4

You can see "You must not use 8-bit bytestrings..." error in the TRAC log (below).

recommended that you instead just switch your application to Unicode strings.

Is there any chance you could locate the pylint warning that is producing the error? I assume it will contain some non-ascii characters. If you post it here then I can attempt to construct a simple test case and commit a fix.
