I'm glad you managed to sort that one out - it had me stumped.  I'll see 
if there's some way to add a version check to the ctags stuff - 
shouldn't be too hard.  As you say, currently you don't get any warning, 
and with all the different versions of ctags around that's A Bad Thing.

They are easy to disable - simply edit the html-head template to not 
include the $modes expression and they will vanish.

Excellent, thank you very much.  I'll add this to CVS.  I can't test 
this out, so if anyone else would like to bash on it that would be good.

The problem is in the http_wash function in Common.pm.  It is used to 
clean up filenames and other data from the web browser before passing it 
to any internal routines.  For security, it's pretty anal about what it 
lets through - and one of the characters it replaces is '+'.  I'm not 
yet sure what the security implications of changing this are, but if you 
can live with the uncertainty then just comment out the line that reads: 
    $t =~ s/\+/ /g;

No idea - line 66 in Generic.pm doesn't even access ctags - the error 
message you quote appears to come from line 102 (as of current CVS 
version of LXR).  Assuming you mean that line, I can't see what could 
cause this to run out of space.  All I can suggest is stepping though it 
in the debugger and seeing what shows up.

This error message is usually caused by not being able to setup the 
configuration properly from lxr.conf.  I'm adding some more diagnostic 
code to Config.pm to help show this up.

You're welcome - and thanks for the Oracle support!
