Sorry, I can't see anything from the log. Can you try to reproduce this and set 
RCB to debul log level?

Thanks

I have the same problem, using the same skin and win7. Using offline scraping, 
everything was working but when I update the list is empty. The nfo files look 
fine, though. Wlll try to create a log.

here is my log, debugging has been enabled. I cant get my list of games back at 
all. Deleting nfo files does not help - they are re-created but the list is 
still empty. I only have 6 or 7 mame roms. Notice that my first import went 
smoothly and the list was displayed. But when I did a re-import everything 
diseappeared. I even tried re-installing rcb. Is there a way to do a complete 
wipe of all data?

I suspect these lines could share some light on the issue:

13:19:36 T:3924 ERROR: Control 58 in window 13000 has been asked to focus, but 
it can't
13:19:36 T:3924 ERROR: Previous line repeats 1 times.

I had the same problem and could fix it by connecting to the games database 
with the sqlite3 command line:

  > sqlite3 ~/.xbmc/userdata/addon_data/script.games.rom.collection.browser/MyGames.db

and truncating the 'rcbsetting' table:

  > DELETE FROM rcbsetting;

Maybe this helps troubleshooting the issue; at least it's a workaround.

Is this at all similar to the issue of letting RCB sit for a while can getting 
this blank screen?

Exiting RCB and going back in fixes things just fine. I can start a new ticket 
if it is a different issue. I have enabled RCB debug info for the next time if 
pops up.

Seems that RCB is reading the attached external devices in some way. See the 
screenshot below, when my external Clonezilla image drive was connected. Note 
the icon on the left, and the main screen:

It happens, when XBMC is starting thread Jobworker, with auto delete set to 
true.

delete: true"

See
https://github.com/beaumanvienna/xbmc/blob/retrorig-pl9/xbmc/threads/Thread.cpp#
L146

I've made a stack trace: http://imgur.com/avD6o1V
After pressing "Continue" xbmc went immediately blank.

In this file here I found some occurrences of "JobWorker", looks pretty 
generic:

This question is, which job actually gets executed.

Here's how you reproduce this bug: Put xbmc in windowed mode and launch a game. 
Make sure xbmc is in the background and play for a while. 5 ~ 12 minutes, about 
2 DKCR level ;-)

I think the bug I just described is a different one then initially reported. 
Sorry for that! It leads to a blank screen as well, but it's recoverable by 
restarting RCB. Tested under Linux Mint 17 and xbmc 14.0 Helix.
