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.

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.
