Hi Jens,
I reported some weeks ago a problem with a plus sign in a path usign
l2h 98.1.pl1

I investigated further only recently, and found this was not the
famous dot and digit bug, it is really a pstoimg bug.
---------- extract from pstoimg (lines 542 to 549) ----------
# LaTeX2HTML may supply a directory: .../tmp/<pid>/
if ($TMP =~ /$dd\w*\d+$dd$/) {
$BASE =~ s/$TMP//;
$DESTDIR = &getcwd;
$DESTDIR .= $dd;
print STDERR "\ncurrent directory is $DESTDIR ...\n" if $DEBUG;
print STDERR "\ntemp directory is $TMP ...\n" if $DEBUG;
} else { $BASE =~ s/^(${dd}tmp)$dd/$TMP=$1;''/e }
-------------------------------------------------------------
The problem lies in the "$BASE =~ s/$TMP//;" line. My path contains
*two* '+' signs in row, and '+' is a special character meaning 'one or
more'. Since the $TMP is in the first part of a substitute command the
specials characters are interprated, and the second signs triggers the
message "nested *?+ in regexp" from perl interpreter.
I suggest to quote the special characters within the path using "\Q"
like this :
$BASE =~ s/\Q$TMP//;
Regards,
Luc
