twisted+gtk gui 很少崩溃

Question

我正在使用twisted with gtk（和gtk2reactor）。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。这些是 Python 能够在我的日志文件中捕获的错误：

上次出现了类似的一系列错误，随后出现了分段错误。我不能确定这是相同的错误，但大致相同。

我使用的是 Python 2.5.2、gtk 2.14.1、twisted 8.1.0。

Answer 1

这些都是所涉及软件的非常旧的版本。请至少升级到 Python 2.6 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，所以你也应该尽可能地升级它。
