Further on my previous email on this subject:
through Special:Export I have verified that the content
of the Windows and Linux installation is, as far as I can
see, identical for pages that fail on Linux. I can't even
begin to fathom where the problem might be.
Each individual element contributing to any given
non-working page seems to work fine in other pages.
I.e., subpages work, templates work, parser functions
work, string functions work.
Invisible characters pages? Might be, as stated here:

I asked the SysAdmin to verify if this problem applies, but
if it doesn't I'm running out of ammo.
Also is this the right syntax to enable logging?
$wgDebugLogFile = "{$IP}/debugLogFile.txt";
Somehow it worked on Windows but not on Linux.
