aqemu crashes w/ Segmentation fault (core dumped)

[Christopher Forster]

Hi, unfortunately aqemu crashed with "Segmentation fault (core dumped)". I would like to re-run the "First Start Wizard" as a result of the terminal output.

Within the console, ran from Terminal:

aqemu

I get the same problem using Ubuntu 13.10 64bit and qemu 1.5.0
I think the bug is caused by a arbitrary list of available qemu/kvm versions in Edit_Emulator_Version_Window.cpp

```
        // Add Items
        if( Emulators[currentRow].Get_Type() == VM::QEMU )
        {
            ui.CB_Versions->clear();

            ui.CB_Versions->addItem( tr("QEMU 0.9.0") );
            ui.CB_Versions->addItem( tr("QEMU 0.9.1") );
            ui.CB_Versions->addItem( tr("QEMU 0.10.X") );
            ui.CB_Versions->addItem( tr("QEMU 0.11.X") );
            ui.CB_Versions->addItem( tr("QEMU 0.12.X") );
            ui.CB_Versions->addItem( tr("QEMU 0.13.X") );
        }
        else if( Emulators[currentRow].Get_Type() == VM::KVM )
        {
            ui.CB_Versions->clear();

            ui.CB_Versions->addItem( tr("KVM 7X") );
            ui.CB_Versions->addItem( tr("KVM 8X") );
            ui.CB_Versions->addItem( tr("KVM 0.11.X") );
            ui.CB_Versions->addItem( tr("KVM 0.12.X") );
            ui.CB_Versions->addItem( tr("KVM 0.13.X") );
        }
```

Similar issue with Ubuntu 13.10, qemu 1.5.0 and aqemu 0.8.2.

Wizard started normally, but I left the last tab unanswered. I'm unable to restart wizard, purging both qemu and aqemu didni't help.

aqemu returns this:

This morning I tried to test aqemu as alternative to qtemu and got this bug. Strace show me that there is problem with read config files. When you remove .emulator files it's start to work, but you lose configration. So after few minutes I found little workaround which work for me:
go to $HOME/.config/ANDronSoft
there are emulator files (e.g. KVM 0.14.X.emulator QEMU 0.14.X.emulator) edit this files if there is twice <Check_Available_Options> tag then remove one and change options from "no" to "yes":

        <Check_Version>yes</Check_Version>
        <Check_Available_Options>yes</Check_Available_Options>
        <Force_Version>yes</Force_Version>

important: you have to change it in all .emulator files you have in this directory

[Ivan Garavito (ivangaravito)]

This doesn't works for Ubuntu 14.04.3 LTS amd64

Kernel: 3.19.0-25-generic-lts-vivid
aqemu: 0.8.2-2
qemu: 2.0.0

Tried change .emulator files and still fails, but erasing these failes opens the GUI.
