扭曲的gtk界面很少崩溃

Question

我用的是twisted with gtk（和GTK2反应堆）。我的应用程序以一种奇怪的方式崩溃。到目前为止，这是它第二次以这种方式坠毁。上一次是大约一个月前。以下是Python在我的日志文件中捕获到的错误：

上次出现了一系列类似的错误，紧接着出现了分割错误。我不能肯定是同样的错误，但有点类似。在

我使用的是python2.5.2、gtk2.14.1和twisted 8.1.0。在

Answer 1

这些都是相关软件的旧版本。请至少升级到Python2.6和Twisted 10.1。我不确定GTK+在Windows上的状态如何，但我知道几年前有一些错误修复，所以你应该尽可能多地升级它。在
