Okay odd, I have not had one of these since late October. Could you tell me which version of indicator sound you are running. This should have been fixed in an SRU which would have went out early November.

[Marc Deslauriers (mdeslaur)]

I was running whatever was in natty on 2011-01-03.

I haven't gotten this since though.

[Conor Curran (cjcurran)]

Okay I'm going to mark this provisionally as fix released. I can't see how the code below at the top of the Draw function could permit a null pointer exception of this nature. The translate gets called directly after this.

draw (GtkWidget* button, cairo_t *cr)
{
  g_return_if_fail(IS_TRANSPORT_WIDGET(button));
  g_return_if_fail( cr != NULL );
.
.

Sorry will mark in progress just to keep it open so that others who may experience this can add their concerns.

let's close it we will get new reports if tghat's still an issue
