GuitarPro SegFault
I installed Arch yesterday and liked it. But Guitar Pro 6 exits a segfault. I did some debuging process and found the problem was libflashplayer. But now i need a shell script to prevent loading flashplayer. I'm a desktop user and i can't uninstall it 
here is the gdb output

Re: GuitarPro SegFault
If you need to prevent loading Flashplayer, you could just move it temporarily before starting GP6, and then move it back afterwards.
Since moving something in /usr/bin will require root priveleges, I have another solution that might work.
#!/bin/bash
# Workaround for Guitar Pro 6 segfaulting due to Flashplayer (?)
# Make sure a directory exists for us.
mkdir -p ~/.gp6-workaround
# Fool PATH locally.
PATH="~/.gp6-workaround:${PATH}"
# Create a false Flashplayer.
ln -T `which true` ~/.gp6-workaround/flashplayer
# Launch GP6
exec guitar-proDoesn't fix the issue, but it's a workaround that should (should) work.

Re: GuitarPro SegFault
I saw the first one before. But it's not a solituon it could damage other running apps. And I dont think the second work. cause guitar pro starts with a shell script that changes the PWD to /opt/GuitarPro6 and load the Qt libraries inside it.And it dont use orginal qt libs.
Anyway, I tryed the script and unfortunately it didnt work.So I've downgraded version that is not include QtWebKit(i dont know how to prevent it find plugins like flashplayer etc.) so dont use flashplugin. It looks the best solution now.
Thanks.

Re: GuitarPro SegFault
You could always use Tuxguitar. Not sure if it loads the new GP format or not (GPX I think).

Re: GuitarPro SegFault
I have a similar problem. Guitar Pro opens up and then closes itself leaving following messages in the console:

Re: GuitarPro SegFault
It is the libqtweb that can not open the libflashplayer.so
Instead update/install the native Qt libraries in to the latest.
After that do:
cd /opt/GuitarPro6
sudo mkdir old_libqt
sudo mv libQt* old_libqt/.
And then start GuitarPro
For me it asked if I wanted to run with the new libraries, click ok and it starts.
No need to downgrade or remove the libflashplayer.so
If above do not work, just copy the libraries back.
