I'm seeing this problem on the last three Wine versions back to 1.1.34. It also affects ie7 through winetricks. I'm running Gentoo and interestingly, it only occurs on my 32-bit machine but not my 64-bit machine. I'm using a 32-bit build of Wine though. The system was more recently updated on the 32-bit machine so maybe that's the real cause. My suspicion lies with glibc, which is 2.11 on the 32-bit machine and 2.10 on the 64-bit machine.
