[wp-hackers] "Plugin could not be activated because it triggered a fatal error." But what is the error?

James mentioned to me he was running 2.9.2. I've looked into this further,
and the issue appears to be that we only started including E_COMPILE_ERROR
in default error reporting (including the plugin activation sandbox) in 3.0.
Additionally, we previously overrode the error reporting level set up via
WP_DEBUG in the sandbox. (In 3.0, we account for WP_DEBUG.) Thus, my guess
is you have another plugin that is defining widget(), which throws the
apparently unreported Zend error.
