This is suspicious. Try to convert a PNM file manually into the PNG format. If that fails, please try to find a working pnmtopng executable and report which netpbm (or pnmtopng) version is failing and which one is working. > > You can test that manually: Simply say > > > > tbl < mixed_pickles.roff > mixed_pickles.tbl > > > > and check whether this call runs successful.

Say gdb --args tbl mixed_pickles.roff then press `r' (and ignore tbl's output to stdout). If tbl crashes, press `bt full' and cut'n'paste the backtrace. Werner
