Audacity fails to launch

[John O'Hagan <johnohagan@iprimus.com.au>]

Hi,

Using up-to-date Etch and Audacity 1.2.4b-2. Recently it silently fails to 
launch. Running in a terminal gives:

Gdk-ERROR **: BadMatch (invalid parameter attributes)
  serial 396 error_code 8 request_code 147 minor_code 3
Gdk-ERROR **: BadMatch (invalid parameter attributes)
  serial 400 error_code 8 request_code 147 minor_code 3

Haven't found this on google or amongst bugs filed against the Debian Audacity 
package.

I have gdk-imlib1 and gdk-imlib11 installed.

Anyone know what this means? 

Thanks,

John
