Exception installing in Software Centre when apt-get is in use

[Nick]

Binary package hint: aptdaemon

I had the command "apt-get install gitk" running and it was at the "Do you want to continue [Y/n]?" prompt. Trying to install a package from Software Centre at this time caused a messageless error dialog to appear, followed by the crash reporter.

I don't expect the package to install while I'm using apt-get, but normally it has a more helpful error message to let me know package management is already happening elsewhere.
