Package: python-libvirt
Version: 0.8.3-4
Severity: normal
Here is an example python script you can use to reproduce the problem:
import libvirt
import sys
def main():
conn = libvirt.openReadOnly(None)
if __name__ == "__main__":
for i in range(0, 10000):
main()
If you run it after a number of connections python will segfault.
Some gdb output
