This bug locks up Thunderbird in the Arch Linux Open Box Manjaro distribution (both 32 & 64 bit) after the update packages below are installed. The error popped up between the last iso image (11-26-2013) and now. The version 28.0 Firefox beta package runs fine. Since Arch Linux is a rolling distribution one (or more) of the listed update packages are causing the error. If I don't install the package updates both Thunderbird and Firefox work fine but they break after the package updates are applied. Someone smarter than me might be able guess which package is most likely to be causing the problem. Here is the update list: There are 195 outdated packages in your system: Name Outdated version Available version acpid [Package ID,typical] 2.0.20-1 [Outdated Version,typical] 2.0.21-1 [New
