[Bug awt/28060] New: segfault in cairoDrawGlyphVector

[hendrich at informatik dot uni-hamburg dot de]

Just for reference, a segfault I got when running jfig on jamvm in gdb
just after loading a figure file ("codesig.fig", requesting Helvetica and 
TimesItalic fonts):



Program received signal SIGSEGV, Segmentation fault.
