          Priority: medium
            Bug ID: 58032
          Assignee: poppler-bugs at lists.freedesktop.org
           Summary: Crash when doing patterns over a mono1 outputdev
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: tsdgeos at terra.es
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: splash backend
           Product: poppler

When running
pdftoppm -r72 -mono over https://bugs.kde.org/attachment.cgi?id=11961 it
crashes when creating the SplashBitmap.

The obvious solution is changing 

  if (rowSize > 0) {
    rowSize += rowPad - 1;
    rowSize -= rowSize % rowPad;
  }

to

  if (rowSize > 0 && rowPad > 0) {
    rowSize += rowPad - 1;
    rowSize -= rowSize % rowPad;
  }

But i'm creating this bug to get Thomas' opinion on it
