Trap in gcc473.dll (yum: Python error and general qt4gui.dll loading error) after update

[aschn]

Yum doesn't work anymore and gives the same error message as in #66.

I installed today, on 2014-02-28, qpdfview and followed the install.os2 hints which packages are required. I executed

yum install libc libgcc4* gcc-stack-protector gcc-stdc++-shared-library gcc-supc++-shared-library libqt4 zlib libjpeg pthread

My last yum update was just after 2014-02-22 10:12 (GMT+1), after I installed Firefox 17.0.5 beta 2.

Additionally, I noticed that qpdfview needs cups.dll and simply copied a recent one into the qpdfview dir. After that, qpdfview started working. I tested it with about 5 PDF files. About half an hour later qpdfview doesn't start anymore. I rebootet and nothing changed. I tested vlc and it traps unkillable. I planned to uninstall the last package changes with yum but yum now just gives the error 87 error (SYS0087: The parameter is incorrect.)

Even the new beta 2 of Firefox 17.0.5 doesn't start anymore, so I looked into popuplog.os2:

epm: D:\ > yum update
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   dlopen rc=87 extra=°

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.6.5 (r265:79063, Jun  5 2013, 16:43:40) 
[GCC 4.4.6]

If you cannot solve this problem yourself, please go to 
the yum faq at:

This might be a duplicate of #66 and #68. Sorry, I haven't seen #68 before posting this bug.

Strange is that all apps worked first. One explanation could be that I probably had the new Firefox open while installing qpdfview and closed it later, so that the gcc dll was unloaded. At the next try with qpdfview the system loaded then the newly installed one, apparently.

How can I revert to the previous state when yum doesn't work anymore? Which .zip package do I need for that?

Thanks

I've just reinstalled yum-bt and several rpm packages and everything is running again, including gcc473.dll. Maybe the error was caused by the netlabs-exp package I had installed before, but I'm not sure.

Because the real bug wasn't found, I leave this ticket open.

see ticket #68 for the real cause. libstdc++ was the problematic one.
