as you see I still have this bug but not all the time. I've already, delete the appstream and install the new one with wget but still get the bug from time to time.... So does anyone have any occurence of this still happens to one of you?
It is really really annoying so please look into this or tell me if I need to reopen a new ticket ? or show you a specific log?

Title:
Refresh hangs indefinitely, appstreamcli using 100% CPU
Status in appstream package in Ubuntu:
Fix Released
Status in appstream source package in Xenial:
Fix Released
Bug description:
[Impact]
* The cache refresh is blocked on a strdup on a non-NULL-terminated string in some very rare occasions (very rare because this bug is present for almost 3y without a single report).
* Fixing this bug resolves the issue for people who might experience it.
* See https://github.com/ximion/appstream/issues/35 for details.
[Test Case 1]
* Run `sudo appstreamcli refresh --force`
* The AppStream cache should be updated, no change in behavior should be seen.
[Test Case 2]
* In case you were experiencing the almost-infinite hang when running
`sudo appstreamcli refresh --force`, this issue should be fixed with
the SRU.
[Regression Potential]
* Very low, since this only fixes the decompression code. There
should be no sideeffects of that (given that the patch itself doesn't
break anything, which it shouldn't, since it has been tested upstream
for a while)
[Other Info]
* This fix has been applied upstream: https://github.com/ximion/appstream/commit/f33c520c37e2ba51d92402220250b8d501a2bf43
* A smaller version of the patch (one-liner) is available, at the expense of not having reduced memory usage: https://github.com/ximion/appstream/commit/378941787d3584b3eb31a6ebe40e0aacc10e180a
