Can not create conditional breakpoint in pytools 1.5 on VS2012


When trying to create a conditional breakpoint in an IronPython or Python project in pytools 1.5.50917.0 in VS 2012 11.0.51106.01 the following message is shown:
"Python does not support breakpoint conditions."

According to and this should be working. Has support been deliberately removed?

You can work around this by modifying the PTVS .pkgdef file to let VS know the feature is supported. You'll find that in [INSTALL_LOCATION]\Extensions\Microsoft\Python Tools for Visual Studio\1.5\Microsoft.PythonTools.pkgdef.

INSTALL_LOCATION is either %localappdata%\microsoft\VisualStudio\11.0 (if you did a per-user install from the advanced page in the installer) or more likely C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ or wherever you installed Visual Studio.

In that file you just need to find:


And add another value below it like:


below the '"CallstackBP"=dword:00000001' and then you just need to run "devenv.exe /setup" so that VS will pick up the change.
