I was trying to merge my scribbles in order to export the file to the PC. When I went to "merge scribbles" the option was available. After pressing the icon the software displays the usual "I am working" animated icon and after a shorter than regular time (usually it take up to 10 seconds to export) you are taken back to the document you were reading.
Other than the sorter time, nothing is abnormal so far.
The problem appears when you go back to file manager and you look for the file that contains the merged scribbles. There is no such a file and, as described above, there was no error or warning message to had told you that something went wrong.
After a couple of unsuccessful attempts I realized that I was reading a read only document! A warning message should be displayed when you try to merge scribbles with such document

PS: The bug list on the wiki page seems very short. As far as I can remember I have seen many minor bugs posted in the forum section. Does anybody filter these bug requests? Should I add this one there? I would rather wait for somebody else to confirm that this is indeed a bug
