This is maverick-specific and 100% reproducible. Seems to be caused by something in goocanvas. Confirming and linking to upstream report.

[Mikael Nordfeldth (mmn)]

I have disabled generating thumbnails and waveforms. The problem still affects me.

[Jeff Fortin Tam (kiddo)]

Wuilmer, do not assign bugs to yourself, unless you intend to *fix* them...

[Wuilmer Bolívar (elwuilmer)]

Jeam i am sorry.!
