Hello,

SInce a couple of days I'm using 2.10 RC1 from the ppa: otto kesselgulasch. I noticed that I am sometimes not able to convert a 8 bit image to 32f. I did:

import 8 bit jpg.
go to image->precision->32 bit floating point. sometimes a window "GIMP debug opens": in that case the conversion seems OK.
other times the GIMP debug doesn't open: in that case GIMP hangs. The progression bar from the conversion
stops at 3/4. After "force quit" I noticed a zombie in the process list (parent is bash)

Good luck!

Wiel

I started GIMP in a bash session . After conversion I got the following:

** (file-jpeg:11929): WARNING **: Directory OlympusCs, entry 0x0101: Strip 0 is outside of the data area; ignored.

** (file-jpeg:11929): WARNING **: Invalid JPEG preview image.

26    ../sysdeps/unix/sysv/linux/read.c: No such file or directory. *WARNING* missing babl fast path(s): "RaGaBaA double" to "R'G'B'A double"

end of bash output======================================
