Ok, better! So there's a problem with dependency check on dnf!

Version-Release number of selected component (if applicable):


How reproducible:

Always

Steps to Reproduce:
1. sudo dnf install gnash-plugin
2. sudo dnf remove (all installed packages in previous step or just gnash-plugin)

Actual results:

Tries to remove other packages like Firefox, xulrunner, etc...

Expected results:

Only remove those packages I selected which aren't hard dependencies.

Additional info:
Comment 1 Rui Miguel Seabra 2014-01-06 19:52:12 UTC 
I only set it to high severity because of dnf's importance!
Comment 2 Ales Kozumplik 2014-01-07 07:04:50 UTC 
Hi, thanks for the report, can you please try to repeat the 'dnf remove gnash-plugin.x86_64' step again using --debuginfo and attaching the result as described by http://dnf.baseurl.org/2013/11/25/reporting-depsolving-bugs/ ?

Thanks.

Result of sudo dnf --debugsolver remove gnash-plugin

Sure, here it is. I didn't actually let it remove the packages and removed with yum so it wouldn't remove too much, but I can repeat that easily if complete removal is preferred.
Comment 4 Ales Kozumplik 2014-01-08 11:07:01 UTC 
Looking.
Comment 5 Ales Kozumplik 2014-01-08 12:12:59 UTC 
This has to do with firefox being tagged as a dependency in DNF's package database. Would you please attach /var/log/dnf.log to this bug?

Here's the excerpt of my dnf.log by the time I did the actions on January 7th.
Comment 7 Ales Kozumplik 2014-01-10 13:23:10 UTC 
Rui, I need the entire dnf.log to determine how firefox got installed. Thanks.
Comment 8 Rui Miguel Seabra 2014-01-10 17:13:30 UTC 
Uh, what? It's Firefox... you know... comes with the Live image? Updated when it's normally updated when Fedora updates it...

The last time was upgraded with dnf upgrade, as usual.
