:SELinux is preventing /home/mikhail/Downloads/navicat101_premium_en/wine/bin/wineserver from using the 'ptrace' accesses on a process.
:*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************
:If you want to allow sysadm to debug or ptrace all processes.
:Then you must tell SELinux about this by enabling the 'deny_ptrace' boolean.You can read 'unconfined_selinux' man page for more details.
:setsebool -P deny_ptrace 0
:*****  Plugin catchall (11.6 confidence) suggests  ***************************
:If you believe that wineserver should be allowed ptrace access on processes labeled unconfined_t by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep wineserver /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2012-07-23 10:45:09 EDT
You have deny_ptrace boolean turned on, so apps are not allowed to ptrace other apps. Looks like opera is doing something wierd, and is denied.  If you do not see any breakage in opera, I would just add a dontaudit for this access or ignore.

If you see breakage and want opera to work, you will need to disable deny_ptrace boolean.

You could also ask opera what it is doing to cause this access.
