canola-conf: can't remove media entries with web ui

[krischan.keitsch at alumni.tu-berlin.de (Krischan Keitsch)]

Hi 

every time I try to remove a media entry from the canola-conf using the web ui  
I get the following error message:

"Unable to process 
request /actions/CnlSystemSettings/get_data/media_collection/scan/is_scanning: 
MochiKit.Async.XMLHttpRequestError("Request failed")"

I would like to remove /media/mmc1 and replace it with /media/mmc1/music. 
However, adding /media/mmc1/music will not work (no error message).

Canola seems not to be scaning at that moment.
Anyone else had this problem and knows how to fix it? 

Thanks 
Krischan
