phantomjs crashes on startup when Qt4 libraries are installed

[Stefan Heim]

phantomjs crashes right on startup:

sheim@ganymede:~$ /usr/lib/phantomjs/phantomjs
PhantomJS has crashed. Please file a bug report at https://code.google.com/p/phantomjs/issues/entry and attach the crash dump file: /tmp/3df6c012-5306-c515-1c955f0d-358d07ce.dmp
Segmentation fault (core dumped)

This is because the linker will use the Qt libraries from libqtcore4:amd64, libqt4-network:amd64, libqtgui4:amd64 and libqtwebkit4:amd64:

sheim@ganymede:~$ ldd /usr/lib/phantomjs/phantomjs | grep Qt
 libQtWebKit.so.4 => /usr/lib/x86_64-linux-gnu/libQtWebKit.so.4 (0x00007f68a8f60000)
 libQtGui.so.4 => /usr/lib/x86_64-linux-gnu/libQtGui.so.4 (0x00007f68a82b3000)
 libQtNetwork.so.4 => /usr/lib/x86_64-linux-gnu/libQtNetwork.so.4 (0x00007f68a7f74000)
 libQtCore.so.4 => /usr/lib/x86_64-linux-gnu/libQtCore.so.4 (0x00007f68a7aa3000)

The phantomjs package comes with own versions of these libraries:

sheim@ganymede:~$ dpkg -L phantomjs | grep 'Qt.*so.4$'
/usr/lib/phantomjs/libQtCore.so.4
/usr/lib/phantomjs/libQtXml.so.4
/usr/lib/phantomjs/libQtWebKit.so.4
/usr/lib/phantomjs/libQtGui.so.4
/usr/lib/phantomjs/libQtNetwork.so.4

Using LD_LIBRARY_PATH, I can get phantomjs to run even if the regular Qt libraries are installed:

sheim@ganymede:~$ LD_LIBRARY_PATH=/usr/lib/phantomjs /usr/lib/phantomjs/phantomjs
phantomjs> phantom.exit();
sheim@ganymede:~$
