So it hangs or crash?

[lill.LEIF (henwo442)]

It crashes. I later saw that I did create a folder before I tried to create
a branch. So I guess the problem is that explorer is trying to create a
folder that already exists. A nice error dialog telling the user his doing
wrong would probably do the trick.

I guess it goes without saying that I'm a beginner on Bzr, but I guess more
people will do the same mistake.

Can you show the output of `bzr plugins` command?

[Gordon Tyler (doxxx)]

I just encountered the same bug on Windows XP SP3 using Bazaar 2.1.0b4 installed from the Win32 installer with the following plugins:

bzrtools 2.1.0b1
    Various useful commands for working with bzr.

explorer 0.10.0
    Version Control for Human Beings.

extmerge
    external merge plugin for bzr

launchpad 2.1.0b4
    Launchpad.net integration plugin for Bazaar.

netrc_credential_store 2.1.0b4
    Use ~/.netrc as a credential store for authentication.conf.

qbzr 0.17.0
    QBzr - Qt-based frontend for Bazaar

rebase 0.5.5
    Rebase support.

svn 1.0.1
    Support for Subversion branches

upload 1.0.0dev
    Upload a working tree, incrementally.

xmloutput 0.8.5
    This plugin provides xml output for status, log, annotate, missing, info,

Looking at the error in Visual Studio's debugger it appears to be an access violation caused by a null pointer. I don't have debugger symbols so I can't really pinpoint it any more than that.

Thanks.

I can provide you debug symbols for bzr own dlls, if it helps. Can you
say is the problem in some bzr dll or in Qt dlls?

[Matthäus G. Chajdas (anteru)]

Well, I'm getting a freeze, even if the branch name is not an existing directory. I simply branch using explorer, and it immediately crashes after branching (i.e. I get the dialog window, see that the branch worked, and then bzr explorer freezes. Win7 tells me to kill the process.

[Matthäus G. Chajdas (anteru)]

Short update, as this might be a different bug actually. On Linux, when I branch from a bound branch, I get a segfault (when using explorer). On Windows, the explorer simply freezes. The source branch is bound to a SVN repository, the target is just a local bzr branch (i.e. bzr branch trunk foo), and trunk is bound to SVN.

[David Roberts (smartgpx)]

I note that the OP is using very old releases, but that this appears to be a duplicate of the older bug:493644 which is apparent with recent releases and has just been confirmed by one of the explorer devs.
