mplib problems

[Peter Rolf]

hi,

does this error message ring a bell? same problem with luatex 0.27 and 
0.28 using the latest beta. mkii works ok.

i also have some problems with endless loops here. luatex (>=0.27) runs 
wild, comsuming one cpu and memory; no error messages or logging. as i 
have currently no time, i simply switched back to an older version. 
0.25.3 works ok, but has a problem with drawing small line widths (seems 
to be fixed in 0.28).
sorry, no time for digging any deeper.

regards, peter

the trunk version seems to have fixed that problem. *thanks Taco!!*
but the 'pen_info' error still occurs at two of my examples.
