commit a9636c580cecfcbe8bfa02d0f9e7ac0bbd257e9d

    screenshot: Remove '/' in screenshot filenames
    
    Make sure we don't use a slash in the pattern for screenshots or we
    wouldn't be able to save the screenshot at all.
    
    Totem-WARNING **: Could not find a valid location to save the screenshot: Failed to find a valid place to 
save
    
    Closes: #427
