Ubuntu Tweak Janitor -> Remove old kernel = crash

[iguest]

Ubuntu 12.04.2, 32-bit can't remove old kernels. I'm using 0.8.5-1~precise2. I have 106 old kernel entries.

Selecting the "Old Kernel" check box produces this message:
Traceback (Most recent call last):
File "/usr/lib/python2.7/dist-packages/ubuntutweak/janitor/oldkernel_plugin.py", line 46, in get_cruft self.emit('scan_finished',True,count,size)
TypeError: could not convert type long to (null) required for parameter 2

Thanks,
Kind regards.

Oh, 106 old kernel entries?

Could you tell me if this is happen every time when you selecting the "Old Kernel" checkbox?
