View as PDF freeze on png BLOB field

Opening BLOB data field that contains png image directly from grid and clicking "View as PDF" icon causes Toad freeze as 100% CPU usage/endless loop and needs force close (no AV/exception).

Other View as.. work as expected, for example Excel shows: Unable to view BLOB data as [Excel]. As it should be because it is png image.

We'll take a look, thanks for reporting this.
