Switching to panel manager FROM the new media panel freezes the phone

---

Phone is with the X1i_GENERIC_UK_CDF1215-1832_R2AA010 ROM and new panel manager

I have the last media panel from the library, but have a recurring issue with it.
As a whole the panel works fine (with the only issue being slow transition from landscape to portrait).
But - if I press the panel button - it freezes the whole phone - it just start to "shrink" the panel and freezes. I tried to take a screenshot, but the My Mobile connection dies as well.

After reset (as the new panel manager loads the last panel) I get the thumbnail of the panel (enlarged)



and can now load the panel selection.

Tried reinstalling the panel and the panel manager, but no improvement.

Somebody with an idea of the cause (and fix if any)?
And if not is it safe to just uninstall the new media panel?
