i edited multiblob.pd and removed the camera source. Instead i added
violoncella.mov as a source (play_video.pd which runs violoncella.mov works
fine.) Now i ran the new multiblob.pd (i've attahced the file) and it doesnt
run. PD crashes giving the following errors:
in dmesg:
 CE: hpet increasing min_delta_ns to 22500 nsec
 pd[9542]: segfault at 4 ip b76be5dc sp bf9eb4f0 error 6 in
pd[9693]: segfault at 4 ip b77e45dc sp bff11a10 error 6 in

using gdb:
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xb7da26c0 (LWP 10295)]
0xb77035dc in __cxa_allocate_exception () from /usr/lib/libstdc++.so.6

using the where command , i've attahced the result.

I've been trying to run something on this for the last 2 weeks. I still
havent been able to. I had issues with Gem also so the whole Gem2GF didnt
work out. Even now when i run a Gem application, it runs but when i try to
destroy the window pd crashes. Hasnt anyone experienced this before??? Is it
a issue with the graphics card(ATI Radeon 4570)?? should i just change the
linux distro(Ubuntu 9.04)?? Has anyone used a distro where all these
features have worked??
