Padre 0.62 crashes if outline Window is active

[wwe]

Windows XP SP3, Strawberry 5.10
(This is perl, v5.10.1 (*) built for MSWin32-x86-multi-thread)
Xaero told me he has the same problem with Strawberry 5.12.
Wx Version=(0.9701) wxWidgets 2.8.10 unicode=(1)

If Padre is running with outline windows active it crashes after first change of the code.

How to reproduce:

• activate View > Show outline
• try to edit this file:

  my $var1;
  my $var2;
  

Without outline window it works fine.

Padre crashes on trunk too.

Ubuntu 10.04:

pete@owl:~/Programming/Perl/Padre?/trunk/Padre$ ./dev.pl -a
Thread 3 terminated abnormally: Can't use string ("File::Spec") as a HASH ref while "strict refs" in use at /home/pete/Programming/Perl/Padre/trunk/Padre/lib/Padre/Document.pm line 935.
Thread 2 terminated abnormally: Can't use string ("pst0

Padre::Task

Padre:") as a HASH ref while "strict refs" in use at /home/pete/Programming/Perl/Padre/trunk/Padre/lib/Padre/Document.pm line 935.

It gets worse..

just type in:

my $var;

and then on the next line my and wait...

pete@owl:~/Programming/Perl/Padre?/trunk/Padre$ ./dev.pl -a

OK, open Padre,

First line:

my $testing;

then my by itself on the next line, wait a bit for the task to kick off... Padre hasn't crashed yet but this is on the console:

/pete@owl:~/Programming/Perl/Padre?/trunk/Padre$ ./dev.pl -a
Thread 3 terminated abnormally: Can't use string ("/home/pete/Programming/Perl/Padr") as a HASH ref while "strict refs" in use at /home/pete/Programming/Perl/Padre/trunk/Padre/lib/Padre/Document.pm line 935.

This is what is spewing into the console currently:

seems that the outline task code is a wee bit broken.

I cannot reproduce the crash on trunk and Ubuntu 10.04, however I also get this kind of message from time to time:

Attempt to free non-existent shared string 'pragmata', Perl interpreter: 0xaf30660 at /home/mrg/src/padre/Padre/lib/Padre/Task/Outline/Perl.pm line 138.
Attempt to free non-existent shared string 'modules', Perl interpreter: 0xaf30660 at /home/mrg/src/padre/Padre/lib/Padre/Task/Outline/Perl.pm line 138.

And this in the end:

Attempt to free non-existent shared string 'Padre::Task::OpenResource?', Perl interpreter: 0xaf30660 during global destruction.

That commit fixes the crash and the errors in the console here.
