Description of problem:

My today's rawhide upgrade resulted into very frequent 'crashing' of firefox.
Running  'firefox -g -d gdb'  -  revealed this backtrace:

Program received signal SIGSEGV, Segmentation fault.

- I've downgraded to:
gvfs-afp-1.26.0-1.fc24.x86_64.rpm     gvfs-smb-1.26.0-1.fc24.x86_64.rpm
gvfs-client-1.26.0-1.fc24.x86_64.rpm  gvfs-1.26.0-1.fc24.x86_64.rpm

and firefox works away (well at least not crashing after trying to safe something:)





Version-Release number of selected component (if applicable):
gvfs-client-1.26.1-1.fc24.x86_64
