added 5. Blank/Erase Disc label
Just ran across this today on Xubuntu 20.04 and Xfburn 0.6.2 when trying Action > Blank CD-RW when the CD-ROM had a CD in it. The workaround is to click No or the close button in the titlebar.
changed title from "Delete" dialog works not properly to Clicking 'Yes' in the full disc erase dialog repeatedly reopens dialog
Seems it was also filed in debian and fixed in #28 (closed).
closed
added 3. Duplicate label
