Package: synergy Version: 1.3.8-1 Severity: normal

Dear Maintainer,

I can reproducibly crash my local synergys by copying text on the synergy client host, then trying to paste it into the Google Chrome URL bar by middle-clicking. When I run

synergys --address 127.0.0.1 --no-daemon

under gdb, I get the following stack trace:

Program received signal SIGSEGV, Segmentation fault.

There are no log messages from synergys immediatly before the crash.

My synergyc is Debian version 1.3.1-5 from squeeze. It is tunnelled over ssh.

Pasting into other applications, for example an xterm, works fine. It is only pasting into Chrome that breaks. And of course, pasting into Chrome from a local selection works.

I can still reproduce the problem using synergyc from the same package version, 1.3.8-1.

I've uploaded 1.3.8-2, with a segfault fix that seems to have fixed a number of reported problems (both in and out of Debian). Can you test with that version, and let me know if you still see the problem?
