[9fans] suffering the same crash in acme

[nemo@gsyc.escet.urjc.es]

Hi,

[ if this should be posted to 9throuble, let me know and ignore
this message. Sorry if that is the case. ]

My acme is dying often arguing that file `endofframe' does not
exist. That may have to do with the fact that acme fails to paint
a rectangle which looks like the last row of characters for the my
column. But perhaps the rectangle unpainted has to do with not
having enough pixels to fill up one more row of text. I don't know.

The stack trace is attached. I haven't found the exact sequence of
actions that cause acme to abort. If I can gather any other useful
data to get this fixed, let me know.

By the way, rio seems to be kept in bad condition after the acme abort.
If I try to delete the window formerly running acme, the system crashes.
[Didn't record the exact diagnostic, but will do in the next crash].

regards
