I'm running Fedora 15 x86_64. Picasa3 would not run, and I was seeing the following when I started Picasa 3 (from a terminal window): [user@puter user]picasa & /usr/bin/picasa: line 189: 14526 Segmentation fault (core dumped) "$PIC_BINDIR"/wrapper check_dir.exe.so /usr/bin/picasa: line 248: 14642 Segmentation fault (core dumped) "$PIC_BINDIR"/wrapper set_lang.exe.so I found these solutions via Google searches: If not done already, install wine: [user@puter user]$ sudo yum -y install wine [sudo] password for user: [enter your password] [Install takes a few minutes] When wine is installed, do the following: [user@puter user]$ cd /opt/google/picasa/3.0/wine/lib/wine/ [user@puter wine]$ sudo mv wininet.dll.so _wininet.dll.so [sudo] password for user: [enter your password] [user@puter wine]$ sudo cp /usr/lib/wine/wininet.dll.so /opt/google/picasa/3.0/wine/lib/wine/ [user@puter wine]$ cd ../../bin/ [user@puter bin]$ sudo mv wine-preloader _wine-preloader [user@puter bin]$ sudo cp /usr/bin/wine-preloader /opt/google/picasa/3.0/wine/bin/ Picasa3 is now working for me. I hope this helps.
