Hi Dan, I think I had the same issue with my plugin and PD 0.47. If I remember well, the solution was to call "sys_startgui(NULL)" after "pd_init()" (it should be in libpd_init() I think).

Digging further, looks like sys_zoomfontwidth() & sys_zoomfontheight() are returning 0 in glist_fontwith()/glist_fontheight().

I’m playing with removing the @synchronized locks in the libpd Obj-C layer since the updates to the libpd ringbuffer seem to be working now.
Long story short, I’m only running into one issue: divide by 0s in g_rtext.c rtext_senditup() when opening a file. It seems that the findx & findy computations on line 215 & 216 fails since the previous glist_fontwidth() & glist_fontheight() calls return 0. Could this be an execution order issue where removing the lock is making something happen earlier than it should?
Adding the following before the findx & findy math works as a quick fix to keep the divide by zero error:
if (fontwidth <= 0) fontwidth = 1; if (fontheight <= 0) fontheight = 1;
I’m wondering if there is a better way to catch this...
