#64 Tk problem in perl5db.pl?

[Leirich Oskar]

I am running the latest Open Perl IDE version with the
Perl5.8 patch installed. The Perl version is 5.8.3 from
ActiveState.
When I have 'use Tk;' in a script and try to compile it
I am getting the error message:
Use of uninitialized value in string eq at
..\..\OpenIDE/perl5db.pl line 519.

Line 519 says:
if ($request eq "STOP") {

Without 'use Tk;' this does not happen.
