python2.5 crashed with SIGSEGV in TclInvokeStringCommand()

[Adam Buchbinder]

Binary package hint: bkchem

Open the attached SVG. Right-click and hold on the 'NH'; select 'Properties' from the popup menu. Python will crash reliably.

As apport reported the bug for Python rather than bkchem, I should mention that I'm running bkchem 0.12.2-1.

I cannot reproduce a crash with bkchem 0.12.5 (Debian experimental).

[Daniel Leidert (dleidert-deactivatedaccount)]

I can't reproduce the issue with bkchem 0.12.2 either. Based on the stacktrace I think, that this is an issue in tcl or blt.

Duplicate of https://bugs.launchpad.net/ubuntu/+source/bkchem/+bug/380346. Having blt with tcl/tk 8.4 makes this segmentation fault reproducible.
