Not just hangs, Nemo crashes when I click on the Windows Network icon.
Clicking on the left side sidebar icon named "Network" (in Nemo|View|Sidebar|Places), shows the Windows Network icon on the right. Double click on the Windows Network icon, and Nemo closes.
As a workaround I installed Gigolo from the repositories, which I've never had trouble with, and can see my other Windows 7 and 8 shares with no problem. The shares even show up in Nemo now on the left places column, and can be drilled into and files copied (largest was 1.1GB) without Nemo crashing. However, even with the shares presenting on the left, when I select Network, then the Windows Network icon on the right, Nemo crashes.
Mint (and Crunchbang when I'm feeling educable) are my go-to workstations. Gigolo works quite well on both so this bug is not a gamechanger, more of an annoyance.
Will be glad to post code if anyone thinks it might be helpful.
