扭曲+ gtk gui很少崩溃

Question

我正在使用与gtk（和gtk2reactor）扭曲。我的应用程序以一种奇怪的方式崩溃。到目前为止，这是第二次以这种方式坠毁。前一次是大约一个月前。这些是Python能够在我的日志文件中捕获的错误：

上次出现类似的一系列错误，然后出现分段错误。我不能确定它是否是同样的错误，但有些问题。

我使用Python 2.5.2，gtk 2.14.1，扭曲8.1.0。

Answer 1

这些都是涉及的软件的所有非常旧的版本。请升级至少Python 2.6和Twisted 10.1。我不确定Windows上GTK +的状态是什么，但我知道几年前有一些错误修正，所以你应该尽可能地升级它。
