Can't open project in GUI "Too many open files"

That looks like the error comes from Qt4 internals, I'm not sure how we can catch it properly.

In the mean time you'd better downgrade bzr-explorer to previous version 1.1.4 as a workaround.

How many files exactly are under the location you're opening with explorer? Does this happen just with a particular location, or whenever you try and open any branch, even a freshly created one?

There are fewer than 50 files. http://bazaar.launchpad.net/~treaves/brewtroller/bt3/files/head:/
If you count the files that it should be ignoring (due to the .bzrignore file) there are more files, as one of the subdirectories is a Doxygen output directory.

This only happens on some projects. Not all.

What's the count including ignored dirs with build artefacts? That is a known issue that needs to get fixed. The linked project certainly doesn't seem huge, so I wonder if there's something else going on too.

4096 or so. Doxygen creates most of them.

Please, test new Bazaar Explorer 1.2.2 release, and tell us whether the problem still exists.

I'll try this out this evening (about 10 hours from now). Thanks.

Still exists.

Can you try this patch, please? Apply it to your copy of bzr-explorer 1.2.2

That does allow it to open.

Thanks much.

so how do we apply the patch??

i type in 'bzr patch workaround-926439.patch'

and it return an error

This still has not made it into a release. Why?

Guys, come on. A critical defect, with a patch that is the better part of two years old? Let's get this promoted. I'm more than willing to do it, just give me access.

Temp fix for MAC Mavericks, update open file limit via terminal:

ulimit -S -n 8048
