Python2.7&bash-fork：内核是用OpenSuse转储的，而不是用Ubuntu转储的

Question

在我的python程序中，我使用Vte终端来派生bash脚本，通过按钮调用。 bash脚本使用wget在互联网上下载一些视频（电视重播下载程序）

import vte

def download(self, dPluzz, donnees=None):
    [...]
    print list_com2 
    self.child_pid = self.v.fork_command(None, list_com2)
    if self.child_pid == -1:
        self.child_pid = self.v.fork_command("/bin/bash", list_com2)
    print self.child_pid

程序在*buntu、14.xx或16.04下运行良好，bash脚本被调用并运行。 当这个程序在OpenSuse上启动时，问题就来了（Tumbleweed，没有尝试其他版本）。 我丢了一个核，窗户关上了：

> python /usr/share/dPluzz/dPluzz.py
['/bin/bash', '/usr/share/dPluzz/dPluzz-cli.sh', '--video-codec', 'copy', '--audio-codec', 'aac', '-d', '/home/guillaume/T\xc3\xa9l\xc3\xa9chargements/', '-u']
2299
Erreur de segmentation (core dumped)

下面是bash脚本的开始（不是我写的，我们是2个开发人员）：

我试图补充 time.sleep（1）在调用bash脚本之前，也尝试过 sleep（1）在bash脚本中，但是没有办法，崩溃追加

我怎样才能看到问题并解决它
