[SOLVED] Bitwig studio error - /dev/shm permissions

I've installed Bitwig Studio demo from the AUR, but am having problems getting it running:

┌─[~ (lap)]─┐
└─[19:10]─> /opt/bitwig-studio/bitwig-studio 
JRE Path: //opt/bitwig-studio/bin/jre
Could not create shared memory with name "bitwig-meter-mem" and size of 16777216
Permission denied
java.io.IOException: Could not create shared memory with name bitwig-meter-mem and size 16777216
	at com.bitwig.base.platform.SharedMemory.a(SourceFile:42)
	at com.bitwig.base.platform.g.<init>(SourceFile:23)
	at com.bitwig.flt.app.FloatMainApplication.<init>(SourceFile:7436)
	at com.bitwig.flt.app.FloatMainApplication.main(SourceFile:5658)

Running strace I've found the system calls that are failing:

19:03:36.094909 unlink("/dev/shm/bitwig-meter-mem") = -1 EPERM (Operation not permitted) <0.000011>
19:03:36.094949 open("/dev/shm/bitwig-meter-mem", O_RDWR|O_CREAT|O_NOFOLLOW|O_CLOEXEC, 0600) = -1 EACCES (Permission denied) <0.000011>

Any ideas how I should go about fixing this?

Thanks

Re: [SOLVED] Bitwig studio error - /dev/shm permissions

those permission denied messages makes me think you started it as root before?

Thanks for the suggestion, I think you might be right.. I deleted the file at /dev/shm and when I run again it appears to have the correct permissions.

Now I get a segfault:

I can say it worked for me (just tried)
I'd try to clear your ~/.BitwigStudio directory.
