[Catalyst] Intermittent blank pages

[Tobias Kremer]

Two days ago I suddenly started receiving intermittent blank pages. Immediately
reloading the page led to the expected response. Looking at the error logs of
the past two days I can see loads of the following error:

Use of uninitialized value in concatenation (.) or string at
/usr/local/lib/perl5/site_perl/5.8.8/Catalyst/Engine/FastCGI.pm line 169.

It appears that there just isn't any body data to process.

This error was absolutely non-existent until a few days ago. AFAICT the only
things that have changed since then is the session table now being InnoDB
instead of MyISAM and Rose::HTML::Form has been updated to the latest version
(5.7014).

Due to there being no additional error messages or warnings I don't know how to
debug this. Does anybody here have an idea what could be going wrong? I'm using
Catalyst 5.7010.

Thanks!
