Hello!
Been using the beta for a while now and this error happens all the time.
When a virus is detected and I click on send to chest the following error occurs
Seek error on file /home/......./.avast/ chest/000001 (large files not supported by stdio)
See attached screenshot.
After clicking on ok the scan continues to run.
Despite the error the infected file is sent to chest.
Operating system = Fedora core 4 x86_64
Also happens on Fedora core 4 (32 bit version)
I’ll take look next week
Hi,
I’ve fixed the bug. The correct version is available at:
http://files.avast.com/files/linux/avast4workstation-1.0.0.tar.gz
http://files.avast.com/files/linux/avast4workstation-1.0.0-1.i586.rpm
Ill give it a try tomorrow. 
I can confirm the send to chest error has been fixed
However I now have another problem.
I can only run avast as root. The error message for non root users is,
Cannot launch entry
Details: Failed to execute child process
“avastgui” (Permission denied)
The problem is in a script, that creates installation packages. Try to manually set permissions at lib/avast4workstation/bin/wrapper-script.sh file to 0755.
You can also try this version:
http://files.avast.com/files/linux/avast4workstation-1.0.1.tar.gz
http://files.avast.com/files/linux/avast4workstation-1.0.1-1.i586.rpm
Ahoy!
I will try the above and report back soon.
Tried the latest rpm package, everything seems to be working fine
I feel a lot safer now 
ok, thx
