[Bug 1300235] Re: init crashed with SIGSEGV

 

James Hunt, I currently have a consistent way of reproducing this.
First, I have both Chromium and Chrome installed as per below in a
fresh+fully updated version of Trusty. Next I opened up Synaptic > typed
in the Quick Filter textbox pepper > highlight pepperflashplugin-nonfree
> click Visit Homepage and this consistently causes a _sbin_init.0.crash
file to appear in var/crash.

For me, the WORKAROUND is just to simply not click the link as the
problem has not been reproducible otherwise so far.

For an example errors crash of this, please see
https://errors.ubuntu.com/oops/341b7c12-8f2f-11e4-b173-fa163e525ba7 .

Let me know if this isn't enough information to reproduce and I can up
the verbosity on my environment.
