When i tried to run my application to record a video from a panasonic ip camera,it run in sometimes and not always.In some cases the program is hanging on th line where i setting up the camera link to gnomevfssrc. g_object_set(G_OBJECT(tdst_Vpipeline->source),"location",path,NULL); where the path is the cameralink. when i tried it with gdb i got, "Detaching after fork from child process 27945." after this line. And the follwing is what i get,when i run it my machine, path setting of panasonic cam *** glibc detected *** ./a.out: double free or corruption (!prev): 0x090f3f68 *** ======= Backtrace: =========

For the crash, please run your application in valgrind with G_SLICE=always-malloc and attach the output here. There seems to be some memory corruption somewhere. For the hanging, please get a backtrace for all threads by using "thread apply all bt" instead of just "bt".
