Comment 6 for bug 624775

The error is triggered by 2 paths with a preserved transform attribute (which seems ignored by Inkscape 0.48 when calculating the extent of 'drawing'):

  <g
     inkscape:label="Ebene 1"
     inkscape:groupmode="layer"
     id="layer1"
     transform="translate(-19.823307,701.09448)">
(…)
    <path
       d="m 620.27385,131.10234 0,21.25984"
       id="path3984"
       transform="translate(19.823307,-701.09448)" />
(…)
    <path
       d="m 619.77362,187.79525 0,21.25985"
       id="path3986"
       transform="translate(19.823307,-701.09448)" />

Forcing a rewrite of the path data of the two paths (e.g. move one step up and back down) converts the preserved into optimized transforms (-> path data) and the extent of 'drawing' is correctly calculated on export to PDF.

The 2 paths possibly had been created on a newer layer (after resizing the page) and moved down to 'Ebene 1' or copied and pasted in place, with preferences set to store transforms in preserved mode.

I haven't yet succeeded to reproduce this bug in a new drawing (with nested preserved transforms on paths).
