Comment 5 for bug 898351

Are you sure that this is an Inkscape Bug and not one of your TeX distribution?
The minimal examples compiles just fine with MiKTeX 2.9 on Windows 7.

The intended linebreak does not appear in the resulting .pdf file, however, because \makebox does not honor "\\". The patch attached to bug #771959 should fix this, by putting everything in a \shortstack environment.
If there are no more compilation problems with recent pdflatex versions, this issue should be closed (or marked as a duplicate of #771959, even though it wasn't intended to be one in the first place).
