[Bug 1279987] Re: usb-creator-gtk crashed with TypeError in __call__(): first argument must be the method signature string: GLib.Variant('a{sv}', {})

[Pascal Garcia]

Hello,
I have also the same problem. But not on all systems.
I Entcounters the proble on a virtualbox VM, but not on a VMWare VM.
But I encounter this problem only when a media is introduced in the dvd reader.
As at some point I reformat the USB stck, I do not know, but I do not think, if the content of the USB stick has any impact.

As long as the dvd reader is empty the software starts with no error and I can complete the creation of the disk based on a iso image.
I did not test to create an image based on a physical media I would have introduces after starting usb-creator-gtk.

Hope that comment will help people to use usb-creator-gtk, and to better
identify the bug.

Regards 
Pascal Garcia
